Reference Wavelengths From Atomic Spectra in the Range 15 Å to 25000 Å

Abstract

This is a compilation of atomic lines with accurately known wavelengths covering the range from 15 Å to 25000 Å. The tables are a fairly complete record of available spectrum lines that meet the requirements for useful references with regard to wavelength accuracy and intensity. In general, wavelength uncertainties range from 0.0001 Å to 0.002 Å. Section 1, λ > 2000 Å, gives λair and λvac for 3341 lines belonging to thirteen different spectra of ten elements. Section 2, λ < 2000 Å, contains 2091 lines belonging to 59 different spectra of 28 elements. The lines of section 2 are listed both by spectrum (i.e. element and ionization stage) and in a finding list arranged in order of decreasing wavelength. Detailed explanations of the data and the sources used for the compilation are included.

Theb1Σ+(b0+) →X3Σ−(X10+,X21) anda1Δ(a2) →X21 Transitions of SbF, SbCl, SbBr, and SbI

“…All gases and chemicals were research grade and were used without further purification. The wavenumber scale of the spectrometer was calibrated by use of Ne I or Ar I reference lines (17). In the medium-resolution measurements reported here, the precision of the measured wavenumbers is on the order of 0.1 cm Ϫ1 .…”

Stark broadening of neutral germanium spectral lines

“…Under Ref., 1 is for Musiol et al (1988) and 2. for Jones & Miller (1974). Kaufman & Edlén (1974). The comparison of semiclassical method of Griem et al (1962) (see also Griem 1974), used in Dimitrijević & Konjević (1983) and the semiclassical perturbation method (Sahal-Bréchot 1969a,b) used here, as well as an explanation of the differences, is given in Dimitrijević & Sahal-Bréchot (1996).…”

Experimental and Theoretical Study of the Electronic States and Spectra of TeH and TeLi

“…Therefore, in the present experiments it could not be decided whether the observed species are formed and excited in the discharge or by chemical reactions in the flowing afterglow. The wavenumber scale of the spectrometer was calibrated by use of emission lines of argon as standards (26). The absolute accuracy of the measurements is thought to be better than 0.01 cm −1 and the relative precision of the wavenumbers of strong lines is on the order of 10 −4 cm −1 .…”
