Tables of Spectral-Line Intensities

William F. Meggers, Charles H. Corliss, and Bourdon F. Scribner

The relative intensities, or radiant powers, of 39,000 spectral lines with wavelengths between 2000 and 9000 Angstroms have been determined on a uniform energy scale for seventy

chemical elements. This was done by mixing 0.1 atomic percent of each element in powdered

copper, pressing the powder-mixture to form solid electrodes which were burned in a 10 ampere,

220 volt direct-current arc, and photographing the spectra with a stigmatic concave grating

while a step sector was rotating in front of the slit. The sectored spectrograms facilitated the

estimation of intensities of all element lines relative to copper lines which were then calibrated on an energy scale provided by standardized lamps, and all estimated line intensities were

finally adjusted to fit this calibration. Comparisons with other intensity measurements in individual spectra indicate that the National Bureau of Standards spectral-line intensities may

have average errors of 20 percent, but first of all they provide uniform quantitative values

for the seventy chemical elements commonly determined by spectrochemists. These data are

presented by element in part I, and all 39,000 observed lines are given in order of wavelength

in part II.

1. Introduction

Spectrochemistry was born a century ago when

KirchhofF and Bunsen [1] ^ definitely demonstrated

that chemical elements were uniquely identified by

spectral radiations, or lines as seen in a spectroscope

provided with a slit. This led immediately to the identification of many chemical elements in the sun and

to the discovery of several new elements, but no quantitative chemical analyses were made until much later.

In 1874, Lockyer [2] stated that "while the qualitative spectrum analysis depends upon the positions of

the lines, the quantitative analysis depends not upon

their position but upon their length, brightness, thickness, and number as compared with the number visible

in the spectrum of a pure vapor". Thus, position (or

wavelength) and brightness (or intensity) are recognized as being the two most important properties of

spectral lines ; wavelengths identify chemical elements

and intensities indicate the concentrations of identified

elements in mixtures or chemical compounds.

During the past century there has been spectacular

improvement in the accuracy of spectral wavelength

determinations; the early ones were limited to 3 or 4

figures, the later use of diffraction gratings and wavelength standards permitted the specification of 5 or 6

figures. Since 1900 the application of interferometers

and better gratings has refined many wavelengths to 7

figures, and recently some 8-figure values of wavelength

standards have been provided. Unfortunately during

this past century very little progress has been made in

assigning uniform quantitative intensity values to

spectral radiations. The great bulk of spectral observations have been made photographically because photographic emulsions provide detailed, permanent records

1 Figures in brackets indicate the literature references on page xil.

of spectra not only in the visible but also in the invisible ultraviolet and infrared regions. But even if

the light source is reproducible and standardized it is

not easy to evaluate the spectral eflficiencies of spectrographs and photographic emulsions so the usual procedure has been to make subjective visual estimates of

relative intensities of spectral lines on an arbitrary

scale based on the relative blackness and/or width of

spectral-line images appearing on a developed photographic plate. Consequently, in thousands of individual

papers and in numerous comprehensive compilations of

spectral data we find only qualitative data on intensities which may have some meaning for adjacent lines

in a given spectrum but none at all when comparing

widely spaced lines, or lines of different spectra of the

same element or of different chemical elements.

In the beginning, most intensity data were reported

on an arbitrary scale of 10 steps, weak lines being

assigned an intensity of 1, and the strongest line intensity 10. Even as late as 1945 extensive new spectral

tables prepared by Gatterer and Junkes [3] displayed

estimated intensities on this limited 1 to 10 scale. Since

1910 some spectroscopists have arbitrarily expanded

this arbitrarily compressed scale. For example, in the

very extensive spectral tables published by Exner and

Haschek [4] the estimated intensities range from 1 to 1000. In wavelength tables compiled by Twyman

and Smith [5] the maximum intensity is 20, in the

compilation of Kayser and Ritschl [6] estimated intensities rise to 4000, and in the well-known M.I.T. Wavelength Tables [7] they soar to 9000. The most recent

compilation of Tables of Spectrum Lines by Zaidel,

Prokof'ev, and Raiskii [8] quotes data from the M.I.T.

Tables and more modern sources but adds nothing

new on spectral line intensities.

Ill
In or about the year 1925, microdensitometers were

developed for the purpose of quantitative measurement

of relative intensities among related lines in multiplets

to test the sum rules derived from the quantum theory

of spectral structure, but no general applications were

made. Since then thousands of spectrochemists have

applied microdensitometers to quantitative chemical

analyses by calibrating intensity ratios of analysis- and

internal-standard lines, but such measurements have

contributed nothing to the basic data on spectral line

intensities. Likewise, with few exceptions, the modern substitution of electronic photodetectors for photographic emulsions has added nothing to our knowledge

of true line intensities over long ranges of different

spectra of many chemical elements.

How may one hope to obtain, with a reasonable

amount of labor, quantitative intensity data on the

same scale for thousands of spectral lines representing

practically all of the metallic elements? A hint was

given in 1874 by Lockyer [2] who observed that "the

lines of any constituent of a mechanical mixture disappeared from the spectrum as its percentage was

reduced." Acting on this suggestion. Hartley [9], in

1884, began to study the spark spectra of metals in

solutions with concentrations of 1 percent, 0.1 percent,

0.01 percent, and 0.001 percent, and proposed a method

of quantitative spectrochemical analysis based on the

lines that could be detected at each dilution. Similar

studies were later made by Pollok and Leonard [10],

by de Gramont [11], and by Lowe [12], all showing

that with progressive dilution of an element its spectral lines weakened and vanished until only the most

sensitive line remained to reveal its presence. In all these works the principle of quantitative spectrochemistry appeared to rest on the number of lines detectable

rather than on their individual intensities. Casual observation must have shown lines of equal strength in

spectra of solutions differing 1000 fold in concentration

but no one mentioned it. It is difficult to understand

why these earlj'^ studies of residual spectra in quantitatively prepared mixtures or solutions did not suggest a method for obtaining physical intensities, but

it is a fact that before our work had begun no one had

attempted to express spectral line intensities as directly

proportional to the number of radiating atoms or con- centration of the element. The present monograph

reports such an attempt [13].

Our method of deriving line intensities from arc

spectra of elements diluted in copper was recently

adopted by Allen [14, 15] to obtain oscillator strengths

of some radiations from 3200 to 5400 A representing

nine elements.

At various times since 1932 we have photographed

the arc spectra of 70 chemical elements diluted in

silver or in copper, and determined the line intensities

of the diluted elements relative to selected lines of the

matrix. An energy calibration of the latter finally led

to physical intensities of 39,000 spectral lines representing 70 elements, all on the same energy scale.

These experiments and results are based on the following propositions, regarded as fundamental for the

quantitative description of residual spectra of diluted

elements excited in ordinary d-c arcs.

1. The limiting detectability of any line is defined

as the atomic concentration that ensures positive detection of the line. This limit is determined mainly by

unavoidable background on a fully exposed spectrogram. The spectrum of an arc burning in air consists

of discrete lines due to atoms, and of more or less

extensive band systems from transient compounds

(usually monoxides), all superposed on a continuous

background arising from thermal radiation of incandescent oxides, from transitions in the continuum, and

possibly from scattered light. This background sets a

limit to the exposure for faint lines that may be given

by any actual spectrograph. If this were not true, the

exposure could be increased indefinitely to compensate

for unlimited reduction in concentration, and detectability would always be infinite. Faint lines are not

recorded by underexposure, and they cannot be recognized on a very dense background produced by over- exposure. In order to guarantee positive recognition

and unambiguous chemical identification a spectral

line should be sufficiently well defined to permit ac- curate wavelength measurement. Experience shows

that the minimum photographic density that meets

this requirement is of the order of 0.05 above that of

the background.

2. The limiting detectability of any element in an

arc depends on the matrix in which the element finds

itself. There is no doubt that in the conventional arc

relative volatilities of the chemical elements as well as

relative ionization potentials affect the relative

strengths of their mixed spectra. In general, the elements with high-vapor pressure and/or low-ionization

potential will be favored in spectral excitation, but

elements with either high or low volatility may be un- derestimated if not uniformly present during the ex- posure, and easily ionized elements may appear less

sensitive because of more complete ionization. In this

connection it must be noted that large differences in

apparent detectability are possible if concentrations are expressed in relative weights instead of numbers

of atoms. Thus, 0.01 atomic percent of boron in

uranium is equal to < 0.0005 weight percent since

the uranium atom is 22 times heavier than the boron

atom.

3. The primary substance (matrix) has no important effect on the relative intensities of lines due to a

secondary substance. It is conceded that the relative

intensities of analogous spectra of different elements,

and of successive spectra of the same element, may

vary with the composition of the samples and/or with

the type, or portion, of light source from which radiaIV
tion is taken, but there is no evidence that the relative

intensities of lines in any particular spectrum of a given element are thereby greatly changed. It may

be expected, therefore, that the relative intensities of

lines observed in one metal arc w^ill remain valid in

any other metal arc, provided the arcs are at approximately the same temperature. The absolute intensities

and the relative strengths of successive spectra may

be altered by excitation conditions. For example, sili- con may be more sensitive in carbon than in calcium,

and it is w^ell known that when easily ionized alkalies are present in sufficient quantity to influence discharge

conditions they reduce the intensity of other spectra,

especially those characteristic of ionized atoms.

4. The order of lines arranged according to decreasing detectability in progressive dilution is the

same as the order of decreasing intensity in the spectrum of the pure element. In other words, emission

line intensities in residual arc spectra (barring selfabsorption) are proportional to the number of radiating atoms; and relative intensities may therefore be

derived from concentrations at which difi'erent lines

show the same intensity or limiting detectability.

Arc spectra usually exhibit a variety of lines, sharp

or narrow ones, diffuse or wide ones (including band

heads), strong ones accompanied by photographic

spreading of developed images, others wide on account

of hyperfine structure, and some partially reversed.

All of these types, except the last, appear in residual arc spectra at low concentrations, and it may be questioned if it is possible to place them on a uniform intensity scale. It may be assumed that if total blackening integrated over the width of the line when recorded

at a moderate level of density be considered in estimating relative intensities these will be on a uniform

scale within the limits of precision in making such

estimates on lines of different types.

5. The order of spectral lines arranged according

to decreasing intensity is the same when the intensities

are decreased by rotating stepped sectors as when the

intensity reduction is produced by successive dilution

of the element in a matrix. This was recognized by

Lowe [12] who published an atlas of spark spectra of

44 elements diluted from 1 percent to 0.001 percent and

later obtained practically the same results by observing

spectra with stepped exposure times [16]. In our

experiments the labor of preparing samples of 70 elements in four or more dilutions was greatly reduced

by adopting only one dilution (0.1 atomic percent) and

then producing further reductions of spectral-line intensities by means of rotating step sectors.

6. Limiting detectability (as defined in 1.) may be

adopted as a physical scale of intensities. Such intensities may be fixed as follows : In a fully exposed spectrogram of copper containing 0.1 atomic percent of

another element any faint but unmistakable line at a given wavelength is assigned unit intensity. Any similar line appearing with unit intensity in a spectrogram

when the energy, or concentration, is reduced to Vs is

said to be 5 times as strong. Thus, all lines can be

assigned relative intensities proportional to their

limiting detectabilities by determining either the

energy reduction or the concentration reduction at

which the stronger lines finally show unit intensity.

The atomic percent concentration at which any line

will show unit intensity then results from dividing 0.1

by its required energy or concentration reduction. For

example, a line of intensity 10 should show plainly at

0.01 atomic percent, while one of intensity 1000 should

be easily seen at 0.0001 atomic percent (one in a

million). Assuming the ratio concentration/intensity

to be constant, the maximum intensity at 100 percent

is easily obtained. Thus, a line of intensity 1000 at

0.1 atomic percent will have an intensity value of 1000

X 100/0.1 = 1,000,000 at 100 percent. This indicates a much larger range of spectral intensities than mentioned heretofore, but it is not unrealistic.

2. Experiments

Whereas all earlier experiments on residual spectra

of diluted elements involved spark excitation of solutions or fused salts, we decided to employ d-c arc

excitation for the following reasons. It has been shown

[17] that the first ionization potentials of some seventy

metallic elements range from 4 to 11 v and the strongest spectral lines of most of these elements have wavelengths between 2000 and 9000 A, which is the spectral

region covered by the present investigations. Furthermore, it is known [18] that the second ionization potential of these elements ranges from 10 to 75 v and

that the strongest lines of singly ionized atoms generally have shorter wavelengths than those of neutral

atoms, nearly half of them being shorter than 2000 A

so that they can be detected only in vacuum spectrographs. Because low-voltage arcs have less ionizing

action than high-voltage sparks more atoms will re- main in the neutral state and, in general, therefore, arc

spectra will exhibit stronger lines and higher sensitivity than spark spectra.

The use of arc spectra in these experiments threatened to introduce errors on account of self-absorption

of radiated energy in the arc aura or envelope which

consists largely of unexcited neutral vapor atoms. In

all spectra of arcs between metal electrodes this is the cause of conspicuous self-reversal of all lines involving

the atom's ground state. However, this is a function

of vapor density surrounding the arc and if this is

reduced to 0.001, self-reversal is usually negligible (see

fig. 2). This is our reason for making these experiments with individual elements diluted in copper in

the ratio 1 to 1000. When ground-state lines of extraV
ordinary intensity were suspected of some self-absorption, intensity ratios were checked or corrected by

examining our earlier spectrograms made with this

element diluted to 0.0002 atomic percent in silver.

2.1. Dilution in Silver

Our preliminary experiments, begun in 1932, can

be described briefly as follows: solutions of known

strength of the elements under investigation were

prepared and proper amounts added to pure silver

oxide, which was then reduced to metal by heating to

make samples containing 8 definite atomic ratios ex- tending from 0.05 to 0.0002 atomic percent of the element added to silver, with a factor of about 2 between

7 successive dilutions. In order to save time and labor,

each series of silver samples incorporated 3 to 6 chemical elements, in addition to zinc which supplied internal

standards. These samples were burned on pure copper

electrodes of a 220 volt d-c arc with 10 amperes. An

image of the arc was projected onto the slit of a stigmatic concave grating spectrograph by means of a fused-quartz lens. Each series of excited samples was

exposed on successive segments of the slit, and was

photographed in four spectral regions ranging from

2000 to 9000 A (see fig. 1). A comparator was employed to measure wavelengths (relative to silver and

copper lines) for the identification of the added elements, and relative intensities of all lines belonging to

residual spectra of diluted substances were estimated

and related to concentration. These results were not

satisfactory for the following reasons : The use of

silver as a matrix and of copper for arc electrodes

precluded the possibility of getting any data for these

two elements or for any lines masked by silver and

copper lines. Also the inclusion of 3 or more elements

in each series of samples resulted in the blending of

many lines, especially in complex spectra, so that it was not possible to assign proper intensities in these

cases. Furthermore, the method of sample preparation and observing appeared to be unsuited to very

volatile elements, or compounds, because no residual

spectra could be recorded for them even at concentrations of 0.1 atomic percent.

2.2. Dilution in Copper

In 1941 these preliminary experiments were abandoned in favor of a modified procedure which led to

satisfactory results. The chief changes in procedure

came with the availability and use of pure metal

powders, and a hydraulic press to form solid electrodes

of mixed powders. Instead of reducing spectral line

intensities to the limit of detectability by successive

dilutions of the element in different samples only one

dilution (0.1 atomic percent) was prepared and line

intensities were reduced by observing through rotating

step sectors. The successful procedure may be outlined as follows: An element under investigation was

mixed with pure copper powder in the atomic ratio

of 1 to 1000. These mixtures were pressed into solid

electrodes, and burned in a 220-volt, 10-ampere d-c

arc which was imaged entirely on the collimator of a

stigmatic grating spectrograph by a lens at the slit. A rotating step sector in front of the slit reduced the

spectral intensities to one-fifth in each of four steps

(see fig. 2). Spectral intensities of the element added

to copper were estimated relative to those of selected

copper lines, and this was done separately for each of

70 elements throughout the range of spectrum from

2000 to 9000 A. The true intensities of the selected

copper lines above 3300 A that served as internal

standards were then measured, by photographic photometry, relative to the known energy distribution in

the spectrum of an incandescent tungsten-strip filament at a certain temperature (see fig. 3). Between

2000 and 3300 A a calibrated hydrogen lamp was used

to determine the relative intensities of copper lines.

Finally the apparent intensities of 39,000 spectral lines

of 70 elements, relative to copper, were adjusted to fit the copper calibrations. These experiments thus provide empirically determined lists of the principal lines

of all elements actually detectable under average conditions in arc spectra when their concentrations are 0.1

atomic percent, and the individual lines bear intensity

numbers approximately proportional to their detectability or their relative energy. That these intensity

numbers really represent physical intensities was

proved by comparing them with earlier, accurately

measured relative intensities of lines in multiplets and

with published relative /-values or oscillator strengths

of- lines in different multiplets extending over a wide

range of spectrum.

In order to provide intensity data for spectral lines

that are partially or wholly obscured by copper lines a

sectored spectrogram of the pure element excited with

self-electrodes, or of a metallic compound or salt exFiGURE 1. Arc spectra of elements (V, Nb, Ta) diluted progressively in silver, and burned on copper electrodes.

cited in a carbon arc, was photographed on every plate

so that any lines blended with copper could be interpolated with proper estimates of their relative intensities. Comparison of relative intensities in copper

and in carbon matrices also supplied new information

on successive spectra, I and II, especially of rare-earth

spectra. Similar data for copper itself were obtained

by using pressed electrodes of pure silver powder to

which 0.1 atomic percent of copper was added, plus

the same quantities of gold and zinc to serve as internal

standards.

Furth,er details of experimental materials, apparatus,

and procedure are given in the following paragraphs.

2.3. Arc Electrodes

For this investigation materials of high purity were

acquired, preferably in the form of metal powders,

although some elements, not available in pure powdered metal form, were obtained as oxides. In every

case the proper amount was added to powdered copper

to produce a mixture in which there was one atom of

the added element to each 1000 atoms of copper. These

mixtures were homogenized by mechanical shaking and

then compressed into solid cylindrical pellets in an

hydraulic press at 5000 psi. The pellets were i/i in. in

diameter, l^ in. in length, and weighed about 1.5 gram.

Two of a kind were mounted in massive water-cooled

clamps in an arc stand and a direct current of 10

amperes passed between them from a 220 v line with

ballast resistance. A 3-mm gap was maintained between the electrodes during the exposures which varied

in duration from 1 sec to 5 min depending on spectrographic efficiency and sensitivity of photographic plates

in different spectral regions.

The arc was imaged on the collimator of a concave- grating spectrograph by means of a quartz lens immediately in front of the slit to obtain uniform illumination along its length and collect light from all parts

of the arc. Rotating step sectors were operated immediately in front of the collecting lens, one with 5 to

1 ratio was used for all line-intensity spectrograms,

but a 2 to 1 step was used for the energy calibration of

copper lines.

2.4. Spectrograph

The dispersing apparatus was a 6-in. grating with

15,000 lines per inch, and 22 ft radius of curvature

in a Wadsworth-type mounting to give stigmatic

images on photographic plates. All observations were

made in the first-order spectrum in which the reciprocal dispersion was 5A/mm, and the practical resolving

power about 50,000 with a slit width of 30 /x.

2.5. Photographic Plates

In order to determine, relative to copper, the intensities of all lines of 70 chemical elements diluted 1000

fold it was necessary to make many hundreds of spectrograms, and to employ 4 varieties of photographic

plates to cover the wavelength range 2000 to 9000 A.

The spectral range 2000 to 3000 A was recorded on

Eastman 103-0 Ultraviolet Sensitive plates, 2600 to

4900 A on Eastman 33 plates, 4600 to 6900 A on Eastman II-F plates, and 6600 to 9000 A on Eastman I-N

plates. Each plate was developed for 4 min in a rocking

tray containing D-19 developer at 70 °F.

The exposure times in each spectral range were

chosen by trial to obtain a suitable continuous background in the first step of the rotating step sector.

Because of variations in spectral sensitivity of photographic materials and in spectrographic efficiency two

exposures of the contaminated-copper arcs were usually

made on each plate, with exposure durations in the

ratio 2 to 1, and the sectored comparison spectrum of

the contaminant was placed between them. Measurements were usually confined to the exposures which

showed the optimum background in the first step of

the rotating sector.

2.6. Energy Calibration of Copper Lines

In order to determine the factors necessary to convert the estimates of apparent intensities of the lines of

70 elements relative to copper into true relative intensities, it was necessary to determine the true relative

intensities of selected reference lines in the spectrum

of copper. The energy calibration of copper lines was

performed as follows:

A G.E. tungsten ribbon filament lamp (type F339-

85, 30 amp, 6v) equipped with a fused quartz window

served as the reference standard of spectral energy

distribution in the wavelength range 3300 to 9000 A.

The brightness temperature of the filament at 6500 A

was measured at two values of filament current by

Henry Shenker in the National Bureau of Standards

Pyrometry Laboratory. The true temperature T of the

filament was determined from the brightness temperature by means of the following equation obtained

from Wien's law

where Cj, = 1.438 cm-deg and A is the product of the

emissivity of tungsten (0.427) and the transmittance

of the quartz window (0.916) at 6500 A.

Table 1. Temperature of tungsten lamp

Current temperature temperature

The energy distribution from blackbodies operated

at these temperatures was taken from tables prepared

by Stair and Smith [19] in the 2300 to 3500 A range,

by Skogland [20] in the 3200 to 7600 A range and by

VIII
Lowan and Blanch [21] in the 7200 to 10000 A range.

The data from these tables were adjusted to a common

basis and multiplied by the emissivity of tungsten and

the transmittance of fused quartz at intervals increasing from 50 A in the ultraviolet to 200 A in the

infrared. The emissivity of tungsten was taken from

a weighted mean curve of published values to which

reference is made by Stair and Smith [19]. The transmittance of fused quartz was calculated from data on

its index of refraction published by Sosman [22] . The

final product, representing the relative energy distribution of the radiation emerging from the quartz window of the lamp, was plotted on a convenient scale to

permit interpolation to any wavelength in the range

2300 to 10000 A.

Spectrograms of the pure copper arc and of the

tungsten lamp were made under conditions identical

with those described above except that for these a 2

to 1 step sector with 8 steps was used for closer calibration (fig. 3). Microphotometer measurements of

transmittance were made in each step of the standardlamp spectrum at intervals of 50 A and a family of

calibration curves of transmittance versus log exposure

(hereafter referred to as log J) was drawn up for each

plate. The exposure of the standard-lamp /, was read

from the calibration curve for each wavelength at a transmittance of 40 percent (where the curve is linear)

and then divided by the calculated intensity Is at that

wavelength. is the calculated intensity emitted by

the standard-lamp. A standardization curve of log Js/h

versus A was plotted for each plate. Calibration curves

of transmittance versus log J were then drawn from

measurements on each of the selected copper lines and

the log exposure (log /, „) of each copper line at a transmittance of 40 percent was read from each curve. Log

Js/h was then subtracted from the average of numerous

values of log /,.„ to give log Z,.,, which is the log of the

true relative intensity of the copper line. The values of

log /c„ from plates in adjacent wavelength regions were

adjusted to a common basis by means of lines common

to both plates. The plot of log Js/h versus A is the

relative response function of the plate-spectrograph

combination and as such was itself useful in the infrared where the copper spectrum lacks lines suitable

for use as an intensity reference.

From 2 to 24 determinations were made on each of

202 lines of Cu I between 2800 and 8100 A with an

average of about 9 determinations per line. The values

of /(.„ obtained by this procedure below 3300 A were

systematically low because of the rapid decline in intensity from the standard lamp in the direction of

short wavelengths. The intensity from the lamp at

5500 A is about 40 times the intensity at 3300 A and

about 300 times the intensity at 2800 A. This fact introduces possible errors from scattered light of the

intense visible radiation which tends to raise and

consequently depress Ic»- The spectrum of copper is composed of sharp lines

and diffuse lines. Since the microphotometer measurements were made at the peaks of the lines rather than

integrated over their widths, the measured intensities

of the two groups of lines are on different relative

scales, the scale of the diffuse lines being smaller than

that of the sharp lines. The reference lines selected for

calibration of the estimates of apparent intensity are

all sharp lines.

The random error of the photometric procedure, including microphotometer error and irregularities of

response of the "N" plates was determined from 92

measurements of apparent relative intensities in spectra of the standard lamp on two plates. The standard

deviation of individual measurements from the mean

was found to be about 1.5 percent. It is probable, therefore, that the uncertainties in these intensity measurements of the copper lines lie entirely in the systematic

errors discussed above and in the random fluctuations

of the arc under study.

Since the ribbon filament lamp was too faint in the

region from 2000 to 3300 A to serve as a standard, recourse was taken to a Hanovia hydrogen arc lamp.

Output from this lamp was compared by R. Stair in

the Radiometry Section of the Bureau with a standard

tungsten-in-quartz lamp and a standard mercury arc

in the region from 2500 to 3800 A; this provided an

independent overlapping calibration which carried us down to 2500 A.

The intensity numbers below 2500 A become less

accurate as the short wavelength limit is approached.

Lacking any reliable energy calibration for shorter

waves, the intensity estimates from 2500 to 2000 A

were necessarily adjusted by judicious extrapolation,

guided by the declining densities of background in the

spectrograms, caused by the increasing absorption in

the apparatus and in the air at shorter wavelengths.

3. Results

Because these relative intensities of 39,000 lines of

70 elements are based on empirical detectability they

will be generally applicable to spectrochemical analysis

provided that proper corrections are made on account

of different excitation in different matrices. Chemical

elements differ in volatility, electron emission, spectral

excitation, and spectral background, and consequently

their spectral detectability in different mixtures or matrices depends on certain controlling factors. One of the

important factors is the atomic ionization potential

which ranges from 3.9 v for Cs to 11.3 v for C, and for

the investigated 70 elements has an average value of 7.3

IX
V. By mixing these 70 elements with copper, which has

an ionization potential of 7.7 v, we obtained excitation

conditions very near the average for all. To convert

our intensity numbers from copper to any other matrix

would require the empirical determination of the

proper conversion factor for each element.

It should be pointed out that sensitivity of detection

in spectrochemical analysis is commonly given in percent by weight. In order to find the weight percent

from the atomic percent given in the tables the following simple relation applies,

r A r-i

where Cu, is the concentration in percent by weight, Ca

is the atomic percent (0.1 in this case), Ac, is the atomic

weight of copper, and Aj, is the atomic weight of the

element X.

Although our original intention was to determine

the relative strengths of many spectral lines from

different chemical elements for purposes of quantitative spectrochemical analysis we believe that the re- sults may also interest theoretical spectroscopists and

astrophysicists. For instance, if our intensity numbers,

based on concentration detectability and relative en- ergy calibration, actually express relative energies

then all may be converted to oscillator strengths, or to

relative gf/'Values, or even to absolute /-values, if the

proper conversion factors can be found.

Because of the low concentration -of each element in

the copper arc from which the spectra were observed,

the lines were extraordinarily free from self absorption. This fact suggests that these emission intensities

could be converted into relative s^/-values, provided

that a valid excitation temperature can be assigned to

the copper arc. The temperature of the copper arc can be determined

by comparing the observed relative intensities of the

lines of an element with the relative gf-YaXxxes, of those

lines [23] , provided that the arc can be shown to be in

local thermodynamic equilibrium for the energy states

under consideration. A preliminary investigation of

this sort has been carried out by using relative gfvalues determined by R. B. King and his coworkers for

Til [24], Tin [25], Vl [26], Cr I [27], Fe I [28],

[29] and Ni I [30] in the region above 3000 A. Figure

4 is a typical example of the correlation of intensities

and s^Z-values indicating the temperature of the copper

arc. The comparison shows that our copper arc is sufficiently in equilibrium to yield a temperature which

may be useful in calculating approximate gf/-values of

some utility from our intensity numbers. A preliminary value of 5000 °K ±300 °K has been obtained

as the average temperature of the 10 amp, 220 v, copper

arc.Because our intensity data represent single (sometimes two) personal subjective estimates of photographic densities in sectored spectrograms there is

no possibility of deriving statistically any probable

errors or standard deviations for individual values.

However, an estimate of the accuracy or reliability of

our data may be obtained by comparing them with

quantitative results published by other investigators.

For example, figure 4 shows the ratios of our intensities

to the relative /-values (or intensities) reported by

King and King [24] who measured the total absorptions of Ti I lines in furnace absorption spectra; they

stated [28] that "The average deviations of the individual intensity measures from the mean values vary

from 4 to 15 percent for different lines" measured between 4 and 16 times on different plates. Each little

circle plotted in figure 4 represents a Ti I multiplet of

1 to 12 lines. The average of 59 deviations from the

mean of all is 25 percent.

A second indication of the reliability of our intensities is obtained by comparing our values with the

relative intensities of lines in multiplets of five elements (Cr, Fe, Mn, Ti, V) measured with photographic

densitometry by Frerichs [31] to test the sum rules.

Such a comparison in 21 different multiplets indicates

deviations ranging from 5 to 22 percent, with an

overall average of 14 percent.

A third estimate of the errors in our data results

from their comparison with photoelectric intensity

measurements in the iron arc by Crosswhite [32] , who

claims an accuracy of the order of 1 percent. The

average difference between intensities of 330 iron lines

(3175 to 5658 A) common to these two sets of observations is ±27 percent, but some of this difference

may be du€ to temperature if this is not the same in

both arcs. Other comparisons could be made but the above three are different and typical ; they suggest that the average

potential of Ti I lines. The temperature of the arc is derived from the

slope of the line which best fits the points.

X
error of our spectral-line intensities within a spectrum of each element is probably between 15 and 25

percent. The uniformity of the intensity scale between the spectra of the various elements is more difficult to assess. Considerable care was taken to obtain

spectrograms under comparable conditions for all of

the elements ; however, differences in volatilities of the

elements or their oxides, and differences in ease of

excitation may possibly result in shifts of intensity

scales between elements. An inspection of the intensities of the strongest lines of the elements indicates

that the values are generally in the same order as

sensitivity of detection of the elements where these are known. Although no high precision was expected

in our mass-production of intensities it is emphasized

that reasonably uniform, quantitative values are now

available for 39,000 lines emitted by 70 chemical

elements.

The tables of spectral-line intensities resulting from

this investigation are presented in two parts. In part I the data are arranged by element in alphabetical order

of chemical name. The heading of each table by element states the atomic symbol, atomic number, atomic

weight, ratio of atomic weight to that of copper, the

electron configuration and term symbol of the normal

state of each spectrum and the corresponding ionization potential expressed in kaysers (cm^). Following

the heading is a selected list of references. Under

Wavelengths are listed all of the sources from which the

wavelengths used in the table were compiled. Under

Classification or Spectrum Assignments are listed the sources from which the assignment of spectrum and

energy levels were obtained. A few spectra showed

bands of metallic oxides. References to data about

these bands are given under Molecular Spectra. In addition a few selected references to published experimental intensity measurements are given under

Intensities.

Following the references there is abstracted from

the main table a list of the strong lines arranged in

order of decreasing intensity and giving, in addition

to the data found in the main table, the electron configurations and spectral term designations of the energy

levels that produce each line. These lists of the strong

lines generally contain 2 percent or more of the lines

in the main table.

Electron configurations and spectral term designations of quantum numbers are of unusual interest in

the production of the strongest spectral lines, or raies

ultimes. According to well-known rules governing the

relative intensities of lines in multiplets, the strongest

line arises from transitions between levels having the

largest / and L values when a/=aL = 1. A rule

relating to raies ultimes was expressed [33] a quarter

of a century ago as follows : "A raie ultime in any spectrum originates with a simple interchange of a single

electron between s and p states, usually preferring configurations in which only one electron occurs in such

states". The above simple rules for the strongest lines

appear to be valid for all spectra.

Then comes the main table, listing in order of wavelength, for every line of an element which appears on

our plates, the intensity, character, wavelength, spectrum, and energy levels. The calibrated intensity numbers in the first column represent the relative radiant

power emitted by our arc at each wavelength. Lines

which differ in profile from a normal sharp symmetrical shape are described in the second column, with the

notation suggested in the Transactions of the Joint

Commission for Spectroscopy [34] as follows:

b — band head,

c — complex,

d — unresolved double line,

h — hazy,

I — shaded longward,

s — shaded shortward,

w — wide.

The wavelengths in column 3 are taken from the places

noted in the list of references and are given to the

nearest 0.01 A. They are all normal air wavelengths,

even those below 2000 A. Column 4 gives the spectrum,

I, II, or III (respectively from neutral, singly ionized

and doubly ionized atoms) in which the line occurs or the

molecule from which a band head originates and column

5 the numerical values, rounded off to the nearest wavenumber, of the levels between which the transition occurs. These data are taken from the Classification reference.

The wavelength of a doubly classified line appears

before the first pair of energy levels and the second

pair follows immediately. In these tables all energy

levels are given in vacuum wavenumber units, cm~\ for

which the name kayser (K) has been proposed [35].

For all spectral lines explained as transitions between

energy levels this serves as a mutual check since the

wavelengths in normal air, when converted to vacuum

wavenumbers by a conversion table [36], will coincide

within one unit with the difference between the two

energy levels. Furthermore these numbers serve as an index to the term designation in "Atomic Energy

Levels" [37] where electron configurations, quantum

numbers, and magnetic splitting factors are given.

A comparison of the excitation energies of any two

classified lines may be made by directly comparing

their larger energy levels in kaysers, and adding the

ionization potentials in the case of lines from II or III

spectra. This direct and simple procedure avoids the

labor of converting all energy levels from kaysers to

electron volts by means of the relation one ev = 8066 K.

In part II the intensity data are arranged in two

tables in order of increasing wavelengths. In table 1

the strong lines of each element which were abstracted from the main tables in part I are here arXI
ranged in order of wavelength. Following this is table

2 in which the individual main tables of part I have

been consolidated into a single table arranged by wavelength. This table contains about 39,000 lines of 70

elements. The intensities in the table are on a scale of

relative radiant power and the scale is the same from

element to element. Following the intensity numbers

are given the wavelength, the element symbol, and

the spectrum. The intensity of a double line appears

before the first wavelength and the second wavelength

follows immediately.

This 'investigation has extended over a period of 28

years, and represents a very considerable amount of

intermittent labor contributed mainly by a relatively

small number of individuals. The program was

initiated by Meggers and Scribner, the latter prepared

diluted-element mixtures, electrodes and spectrograms,

while the former identified wavelengths, supplied many

line classifications, and estimated relative intensities

of some fifty thousand lines. In the production of the

mixtures and the copper electrodes and spectrograms

valuable assistance was given by Harriet E. Brown.

Corliss contributed the copper calibration, the conversion of apparent intensities to relative radiant powers,

and prepared the final tables. Mrs. Ruth Peterson carefully prepared and checked all the data on IBM cards

so that it could be printed automatically. Valuable

advice and assistance on the IBM machine operations

was given by William Bozman. To all our able and

reliable assistants the authors extend their sincere appreciation and thanks for cheerful and conscientious

cooperation.
