Notes

1According to Katti and Korwar, 1974 also observed in emission.
2Natural Sn isotopic mixture.
3Originally assumed to be 2Delta, this state has recently been reinterpreted as 4Sigma- (Omega = 1/2 and 3/2) on the basis of a tentative analysis of incompletely resolved rotational structure Chatalic, Iacocca, et al., 1973, 2.
4Lambda-type doubling Delta vfe = -0.009(J+1/2) Chatalic, Iacocca, et al., 1973.
