Notes

1The revised vibrational analysis of the B ← X1 system by Cordes and Gehrke, 1966 leads to the expression ν = 34937.5 + 386.3(v'+1/2) - 1.36(v'+1/2)2 - 300.8(v"+1/2) + 1.04(v"+1/2)2 Cordes and Gehrke, 1966 and ν00 = 34980.2 Cordes and Gehrke, 1966.
2Diffuse bands (prediss.)
3Tentative rotational analyses Rao and Rao, 1964, Singh and Singh, 1968.

5See Wieland and Newburgh, 1952 for a discussion of this value.
6From an electron impact study of PbCl2 by Hastie, Bloom, et al., 1967, 2 who have also determined the electron affinity of PbCl, E.A. = 1.0 eV.
