Notes
| 1 | All constants for these states are derived from laser-excited fluorescence spectra. In carrying out the analysis it was necessary to assume the value of the rotational constant Be for the ground state Ahmed, Barrow, et al., 1975, see 4. |
| 2 | From the B1 → X1 and B1 → X2 flourescence series. |
| 3 | Combined results from fluorescence and absorption spectra. |
| 4 | Estimated value Ahmed, Barrow, et al., 1975 assuming re (TeSe) ~ 1/2[re(Te2)+re(Se2)]. |
| 5 | Thermochemical value (mass-spectrometry) Porter and Spencer, 1960, corrected for new values of D00(Se2) and D00(Te2). |
| 6 | The band structure is somewhat diffuse suggesting predissociation Joshi and Sharma, 1967, Ahmed, Barrow, et al., 1975. |
