Notes
| 1 | Complex system of emission bands; tentative vibrational analysis Rao, 1949. |
| 2 | Absorption cross sections Davidovits and Bellisio, 1969. |
| 3 | Continuous absorption with maximum at 39820 cm-1, preceded by diffuse bands of longer wavelengths. |
| 4 | Vibrational constants of Miescher, 1941 whose measurements at higher dispersion are more extensive than those of Howell and Coulson, 1938. Rotational analyses Barrow, 1957 give ΔG'(1/2) = 201.60 Barrow, 1957, ΔG"(1/2) = 281.88 Barrow, 1957. |
| 5 | ωeze = -0.115. |
| 6 | Predissociation for v' ≥ 4; see Miescher, 1941. |
| 7 | From De Wijn, 1965 who gives rotational constants for all four TlCl isotopes. See also Lovas and Tiemann, 1974. |
| 8 | Vibration sp. 12 |
| 9 | μel = 4.5153 + 0.05527(v+1/2) + 0.000078(v+1/2)2 D Ley and Schauer, 1972; from Ley and Schauer, 1972 who give also hfs constants and magnetic parameters for v = 0...3. |
| 10 | Photoionization mass-spectrometry Berkowitz and Walter, 1968; good agreement with thermochemical and spectroscopic values Barrow, 1960, Barrow, 1960, 2, electron impact mass-spectrometry Khvostenko and Sultanov, 1965, and flame photometry Bulewicz, Phillips, et al., 1961. |
| 11 | Photoionization value Berkowitz and Walter, 1968. As for TlBr, this adiabatic potential corresponds to the second rather than first vertical potential observed by photoelectron spectroscopy Berkowitz, 1972. |
| 12 | IR and Raman spectra in argon and krypton matrices. |
| 13 | D00(TlCl) + I.P.(Tl) - I.P.(TlCl). |
