Data are included for observed transitions of 99 elements and energy levels of 52 elements. The most current NIST-evaluated data associated with each transition are integrated under a single listing. Spectra of Gas Discharges Color images of spectra of gaseous elements undergoing electrical discharge excitation. Resulting from a critical evaluation of the published literature, the database contains over 19,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. A highly interactive program allows the user to search by element, line type, line energy, and many other variables.
Users can easily identify unknown measured lines by matching to previous measurements.
