Notes

1Photoionization mass-spectrometry Berkowitz and Walter, 1968; good agreement with thermochemical results [ Barrow, 1960 and references given in Berkowitz and Walter, 1968]; similar results by equilibrium mass-spectrometry Murad, Hildenbrand, et al., 1966 and flame photometry Bulewicz, Phillips, et al., 1961.
2Adiabatic potential from the photoelectron spectrum Dehmer, Berkowitz, et al., 1973.
3According to Barrow, 1960 [see Table 3, Note c of this reference) the vibrational analysis is uncertain and the 0-0 band may lie at 45010 cm-1.
4Both A and B have small potential humps of ~ 0.18 eV.
5D1 = 5.22E-7, D2 = 6.73E-7.
6 Dijkerman, Flegel, et al., 1972
7IR and Raman spectra in argon and krypton matrices.
8muel = 4.1936+ 0.0691(v+1/2) D Boeckh, Graff, et al., 1964; gJ = -0.05356 muN Boeckh, Graff, et al., 1964.
9D00(TlF) + I.P.(Tl) - I.P.(TlF).
