Green emission "bands" near the Rb 6s-5s and 4d-5s forbidden transitions Tam, Moe, et al., 1975; similar features observed in absorption Besombes, Granier, et al., 1969.
Potential curves for the four following states have been constructed from studies of the far-wing emission spectra of the Rb resonance lines Drummond and Gallagher, 1974 Carrington and Gallagher, 1974. Near-wing intensities have been measured by Ottinger, Scheps, et al., 1975. Only the A 2Pi curves have distinct potential wells with De ~ 330 cm-1 and re ~ 3.35 Å.

Notes

1An average value gamma bar= 3.5E-6 cm-1 Bouchiat, Brossel, et al., 1975 for the spin-rotation interaction constant has been derived from relaxation measurements on optically polarized Rb atoms in Ar Bouchiat, Brossel, et al., 1975.
