Notes. Wavelengths are in ångströms and energy in electron volts, eV. i and k indexes lower and upper states, respectively. (a) Data retrieved without wavelength restrictions and transitions are calculated without fine structure. (b) Compiled from multiple sources over several months. (c) Observed and Ritz wavelengths. (d) Vacuum wavelengths. (e) Provided as gf not log (gf). (f) Energy in cm−1. (g) Energy in Ry.
