Notes

1 Chandler, Hurst, et al., 1965 give, without details, G(1/2) ~ 458 for 128Te0. Haranath, Rao, et al., 1959, by contrast, suggest omegae = 408, omegaexe = 4.0. According to Chandler, Hurst, et al., 1965 this state is predissociated between v=2 and 3.
2Extensive perturbations.
3DeltaG(3/2)=409.9, DeltaG(5/2)=393.4, DeltaG(7/2)=364.53. From v=3 to 10 the vibrational intervals are quite well represented by omegae(3 leq v leq 10) = 410.71, omegaexe(3 leq v leq 10) = 5.772; large deviations occur below and above these limits. Vibrational levels observed to v = 15. The v' numbering has been established from isotope shifts Chandler, Hurst, et al., 1965 and has been increased by +3 units compared to the numbering used by Shin-Piaw, 1938 and Haranath, Rao, et al., 1959.
4Absorption lines become diffuse above J' ~ 42 and 14 in v'=9 and 10, respectively; the highest observed level in emission is v'=9. The predissociation limit (~31450 cm-1) is assumed to correspond to normal atomic products.
5Estimated Barrow and Hitchings, 1972 from the magnitude of their Omega-type doubling in X2 1 (see 6).
6B(1+) - B(1-) ~ +0.00066 Barrow and Hitchings, 1972.
7From the predissociation in A1 0+ (see 4).
8From the photoelectron spectrum Potts and Williams, 1976.
9D00(TeO) + I.P.(Te) - I.P.(TeO).
