Foreword

The National Standard Reference Data System provides access to the quantitative data of physical science, critically evaluated and compiled for convenience and readily accessible through a

variety of distribution channels. The System was established in 1963 by action of the President’s

Office of Science and Technology and the Federal Council for Science and Technology, and

responsibility to administer it was assigned to the National Bureau of Standards.

NSRDS receives advice and planning assistance from a Review Committee of the National

Research Council of the National Academy of Sciences-National Academy of Engineering. A number of Advisory Panels, each concerned with a single technical area, meet regularly to examine

major portions of the program, assign relative priorities, and identify specific key problems in

need of further attention. For selected specific topics, the Advisory Panels sponsor subpanels

which make detailed studies of users’ needs, the present state of knowledge, and existing data re- sources as a basis for recommending one or more data compilation activities. This assembly of

advisory services contributes greatly to the guidance of NSRDS activities.

The System now includes a complex of data centers and other activities in academic insti- tutions and other laboratories. Components of the NSRDS produce compilations of critically

evaluated data, reviews of the state of quantitative knowledge in specialized areas, and computations of useful functions derived from standard reference data. The centers and projects also

establish criteria for evaluation and compilation of data and recommend improvements in ex- perimental techniques. They are normally associated with research in the relevant field. The technical scope of NSRDS is indicated by the categories of projects active or being

planned: nuclear properties, atomic and molecular properties, solid state properties, thermodynamic and transport properties, chemical kinetics, and colloid and surface properties.

Reliable data on the properties of matter and materials is a major foundation of scientific

and technical progress. Such important activities as basic scientific research, industrial quality control, development of new materials for building and other technologies, measuring and correcting

environmental pollution depend on quality reference data. In NSRDS, the Bureau’s responsibility

to support American science, industry, and commerce is vitally fulfilled.

Preface

The present publication is the fifth Section of a series that is being prepared in response to the

increasing demand for a current revision of two sets of tables containing data on atomic spectra

as derived from analyses of optical spectra.

The first set. Atomic Energy Levels, NBS Circular 467, consists of three Volumes published,

respectively, in 1949, 1952 and 1958. This Circular has been reprinted as NSRDS-NBS 35, Volumes

1,11, and III. The second set consists of two Multiplet Tables; one published in 1945 by the Princeton University Observatory, containing multiplets having wavelengths longer than 3000 A; the other.

An Ultraviolet Multiplet Table, NBS Circular 488, appearing in five Sections, the first in 1950,

the second in 1952, and the others in 1962. The Princeton Multiplet Table was reprinted in 1972

as NSRDS-NBS 40.

The present series includes both sets of data, the energy levels and multiplet tables, as parts

A and B, respectively, for selected spectra contained in Volume I of “Atomic Energy Levels.”

The Sections are being published at irregular intervals as revised analyses become available. A

flexible paging system permits the arrangement of the various Sections by atomic number, regardless of the order in which the separate spectra are published. Section 1 includes three spectra

of silicon, Z = 14; Si II, Si III, Si IV. Section 2 contains similar data for Si I. Section 3 covers all spectra of carbon, Z = 6: C I, C II, C III, C IV, C V, C vi. Section 4 includes the last four spectra

of nitrogen, Z = 7: N IV, N V, N VI, N VII. The present Section, 5, completes the spectra of nitrogen,

N I, N II, N III. Section 6 contains the spectra of hydrogen, Z = 1: H I, D, T. The form of presentation

of the data is described in detail in the text of Section 1. All Sections are arranged identically, and

the same conversion factor, cm"1 to eV, 0.000123981 is used throughout.

The manuscript has been prepared by Charlotte E. Moore, who has published the earlier tables.

She appreciates the cordial cooperation of numerous atomic spectroscopists. She is particularly

indebted to colleagues in Sweden, B. Edlen, K. B. S. Eriksson, K. Bockasten and R. Hallin, for their

helpful guidance and for providing valuable data on analyses in advance of publication. Similarly,

D. J. Michels has generously furnished his unpublished thesis material including short-wave observations. W. C. Martin and his associates in the Spectroscopy Section have given helpful advice

regarding the text and tables. To all the writer extends grateful thanks.

Most of the revised and extended analysis is from the work of K. B. S. Eriksson and J. E.

Pettersson, who kindly furnished their final manuscripts in advance of publication. Additional

levels are quoted from the 1966 and 1961 papers from Lund.

A further revision and extension of the analysis based on observations by M. S. Manalis

and new measurements in the vacuum ultraviolet region, have been provided by K. B. S. Eriksson

(1974). He reports 74 new energy levels together with 147 newly classified lines between 3781 A

and 9022 A and 56 between 864 A and 1172 A.

Eriksson points out that the total orbital angular momentum tends to be a good quantum

number for the nf— and ng— configurations. Consequently, the listed designations for the pairs

include the respective letters D,F,G and F,G,H for these configurations.

The sextet terms from the 25 2p3

( 5 S°)n/ configuration are not connected with the other terms,

as indicated in the table by The np-series of quartet terms from this limit have been observed

in absorption by Carroll and his associates from n = 3 to 14. The lines occur in the region 612 A to 694 A as combinations with the ground term. All of the lines are broadened as a result of autoionization. The term with n — 9 is entered in brackets because the N I line coincides with a line

of Ne I. The levels from the 2s2 2p

2

( 3 P)6/ configuration are based on infrared observations by J. W.

McConkey and his associates.

The classified lines extend from 864 A to 18751 A. They include two lists of calculated wavelengths: one of 78 lines published by V. Kaufman and J. F. Ward, and a more recent compilation

by K. B. S. Eriksson of 147 lines, in the range 885 A to 1745 A. These lists are in excellent agreement.

Both B. Edlen and G. Herzberg have provided earlier, more limited lists of N I lines that are

suitable for use as standards.

The limit is from the 1971 paper by K. B. S. Eriksson and J. E. Pettersson. The value

of 117356.46 ±0.12 for 25 2 2p 23 P2 was determined from the levels nd 4 F<q (n = 3-6) and n/G[5j5j

(n — 4—6) by a Ritz formula, with R = 109733.01. The quoted limit was then derived ‘‘from the known

structure of the N II ground configuration.”

J. W. McConkey and J. A. Kernahan used the nflevels to obtain ionization limits for the ground

term of N II. Their value 117225.35 cm -1 differs very little from the limit quoted above.

Brackets indicate predicted values of energy levels.

The terms are from the revised and complete analysis of K.B.S. Eriksson, who has reobserved

the spectrum from 2077 A to 10547 A and measured some 450 lines. He has added approximately

200 classified lines and 55 new levels to the earlier work. In the vacuum region improved wavelengths from older spectrograms are given for 15 fines.

Observed intersystem combinations connect the terms of different multiplicities, and the

consistent system of term values provides accurate recalculated wavelengths in the region short

of 2000 A.

An evident misprint occurs in the published value of the term 5s 1 PJ

I . The observed combinations indicate a correction of —0.61 cm-1

, which has been introduced in the table. The level

5c/ 3 D£ has, also, been added on the basis of one observed combination.

The table of observed ^-values is taken from Volume I of “Atomic Energy Levels,” since no

later Zeeman data are available.

The ionization limit is well determined from selected members of the nf series (n = 4 to 7). REFERENCES

The early analysis has been extended by D. J. Michels who has observed N in in the shortwave region from 208 A to 482 A. K. B. S. Eriksson reported the present interval of the ground term. B. Edlen and his associates

observed the intersystem combination in Multiplet UV 0.01 and derived a correction of — 5.0 cm -1

to the quartet terms. This has been adopted by D. J. Michels and is included here.

The analysis has been further improved and extended by the observations of R. Hallin and his

o o associates in the range 763 A to 8424 A. A revised list of term values and multiplets based on this

material has been kindly furnished by K. Bockasten especially for inclusion here. He and G. Arrhen

have also provided a preliminary manuscript in which “a check of the relative positions of the 4

/'

levels has been obtained from formulas for the sp/-configuration”.

The limit ( X S) has been determined from the ng-terms (n = 5, 6, 7) and nh-terms {n = 6, 7), by

means of the polarization formula, by using the method of least squares, according to K. Bockasten.

In column 3 parentheses indicate that the estimated intensities are on a different scale than those without

parentheses. For wavelengths shorter than 482 A the intensity estimate reported by Michels for the leading line of a multiplet is entered for the entire multiplet and indicated as a blend, for unresolved groups.

New Multiplet Numbers, not inserted between older ones, start with UV 31 and 18.

NBS TECHNICAL PUBLICATIONS

PERIODICALS JOURNAL OF RESEARCH reports National Bureau

of Standards research and development in physics,

mathematics, and chemistry. It is published in two sections, available separately:

• Physics and Chemistry (Section A)

Papers of interest primarily to scientists working in these fields. This section covers a broad range of physical and chemical research, with major emphasis on

standards of physical measurement, fundamental constants, and properties of matter. Issued six times a year. Annual subscription: Domestic, $17.00; Foreign,

$21.25.

• Mathematical Sciences (Section B)

Studies and compilations designed mainly for the mathematician and theoretical physicist. Topics in mathematical statistics, theory of experiment design, numerical analysis, theoretical physics and chemistry, logical

design and programming of computers and computer

systems. Short numerical tables. Issued quarterly. Annual subscription: Domestic, $9.00; Foreign, $11.25.

DIMENSIONS/NBS (formerly Technical News Bulletin) —This monthly magazine is published to inform

scientists, engineers, businessmen, industry, teachers,

students, and consumers of the latest advances in science and technology, with primary emphasis on the work at NBS. The magazine highlights and reviews such

issues as energy research, fire protection, building tech- nology, metric conversion, pollution abatement, health and safety, and consumer product performance. In addition, it reports the results of Bureau programs in measurement standards and techniques, properties of matter and materials, engineering standards and services, instrumentation, and automatic data processing.

Annual subscription: Domestic, $9.45; Foreign, $11.85.

NONPERIODICALS

Monographs—Major contributions to the technical liter- ature on various subjects related to the Bureau’s scientific and technical activities. Handbooks—Recommended codes of engineering and

industrial practice (including safety codes) developed

in cooperation with interested industries, professional

organizations, and regulatory bodies.

Special Publications—Include proceedings of confer- ences sponsored by NBS, NBS annual reports, and other

special publications appropriate to this grouping such

as wall charts, pocket cards, and bibliographies.

Applied Mathematics Series—Mathematical tables,

manuals, and studies of special interest to physicists,

engineers, chemists, biologists, mathematicians, computer programmers, and others engaged in scientific and technical work.

National Standard Reference Data Series—Provides

quantitative data on the physical and chemical properties of materials, compiled from the world’s literature and critically evaluated. Developed under a world-wide

program coordinated by NBS. Program under authority

of National Standard Data Act (Public Law 90-396).

NOTE: At present the principal publication outlet for these data is the Journal of Physical and Chemical

Reference Data (JPCRD) published quarterly for NBS

by the American Chemical Society (ACS) and the American Institute of Physics (AIP). Subscriptions, reprints,

and supplements available from ACS, 1155 Sixteenth

St. N. W„ Wash. D. C. 20056.

Building Science Series—Disseminates technical infor- mation developed at the Bureau on building materials,

components, systems, and whole structures. The series presents research results, test methods, and performance criteria related to the structural and environmental functions and the durability and safety characteristics of building elements and systems.

Technical Notes—Studies or reports which are complete

in themselves but restrictive in their treatment of a

subject. Analogous to monographs but not so comprehensive in scope or definitive in treatment of the subject area. Often serve as a vehicle for final reports of work performed at NBS under the sponsorship of other government agencies.

Voluntary Product Standards—Developed under pro- cedures published by the Department of Commerce in Part 10, Title 15, of the Code of Federal Regulations.

The purpose of the standards is to establish nationally

recognized requirements for products, and to provide

all concerned interests with a basis for common under- standing of the characteristics of the products. NBS
