Notes
| 1 | Chandler, Hurst, et al., 1965 give, without details, G(1/2) ~ 458 for 128Te0. Haranath, Rao, et al., 1959, by contrast, suggest ωe = 408, ωexe = 4.0. According to Chandler, Hurst, et al., 1965 this state is predissociated between v=2 and 3. |
| 2 | Extensive perturbations. |
| 3 | ΔG(3/2)=409.9, ΔG(5/2)=393.4, ΔG(7/2)=364.53. From v=3 to 10 the vibrational intervals are quite well represented by ωe(3 ≤ v ≤ 10) = 410.71, ωexe(3 ≤ v ≤ 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. |
| 4 | Absorption 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. |
| 5 | Estimated Barrow and Hitchings, 1972 from the magnitude of their Ω-type doubling in X2 1 (see 6). |
| 6 | B(1+) - B(1-) ~ +0.00066 Barrow and Hitchings, 1972. |
| 7 | From the predissociation in A1 0+ (see 4). |
| 8 | From the photoelectron spectrum Potts and Williams, 1976. |
| 9 | D00(TeO) + I.P.(Te) - I.P.(TeO). |
