Line Tables

These tables give observed air wavelengths for the 2000-20000 Å range for spectra other than Fr I. Outside of the 2000-20000 Å range, the wavelengths are vacuum wavelengths. Lines of Fr I are extrapolated vacuum wavelengths from known energy levels. All observed lines are from NIST ASD. All energy level information is from NIST ASD. Wavelengths from MIT Wavelength Tables have been omitted as this publication appears to still be under copyright. However, in some cases, the exact same wavelength is given by NIST and MIT; in that case, the line is included.

Line intensities have been adjusted in the visible region to match photographed visible spectra. Line intensities of Rn have been adjusted to match the Grotrian diagram of Rn I. Line intensities in the infrared and ultraviolet are less reliable, but every effort was made to estimate them as accurately as possible. The elements He, O, Cl, Ar, Kr, and Xe have had their NIR lines photographed out to roughly 11000 Å. The intensities of the "brightest" several IR lines of each of these elements, in the 7000-10000 Å range, can be trusted. For the range of 800-8000 Å, estimated visual brightnesses (EVB) are given. A dash in either of the intensity columns means the line intensity would be less than one relative to other lines of the same spectrum.
