Notes
| 1 | Observed in emission in the reaction of metastable rare gas atoms with fluorine containing molecules Velazco, Kolts, et al., 1976, Velazco, Kolts, et al., 1977 and in electron-beam excited mixtures of Ar+Xe+F2 at high total pressure Brau and Ewing, 1975. Asorption in inert gas matrices at similar wavelengths Ault and Andrews, 1976. Laser-excited emission spectra in solid Ne and Ar Goodman and Brus, 1976; lifetimes of 12.5 and 11.5 ns, respectively, have been measured. |
| 2 | Lifetime τ ~ 18.8 ns Burnham and Harris, 1977; Goodman and Brus, 1976 measure τ= ~ 6 ns Goodman and Brus, 1976 in solid Ar. |
| 3 | Observed in emission at low pressure in the reaction of metastable (3P2) Xe atoms with F2, NOF, N2F4, CF3OF [flowing afterglow Velazco and Setser, 1975, Golde, 1975] and at high pressure (of the order XeF of 1 atm) on electron bombardment of mixtures of Ar, Xe, and F2 or NF3 Ault, Bradford, et al., 1975, Brau and Ewing, 1975, Tellinghuisen, Tisone, et al., 1976; two bands (0-3 and 1-4 according to the new v" numbering) at 3532 and 3511 Å show strong laser action Ault, Bradford, et al., 1975, Brau and Ewing, 1975, 2, Tellinghuisen, Tisone, et al., 1976. Also observed in fluorescence in the photolysis of XeF2 Brashears, Setser, et al., 1977. In emission and absorption in inert gas matrices Ault and Andrews, 1976, Goodman and Brus, 1976. |
| 4 | Tentative interpretation Ault and Andrews, 1976 of observations in solid argon. |
| 5 | Unstable |
| 6 | The v" numbering in Tellinghuisen, Tisone, et al., 1976 has been changed in a "note added in proof". See also Velazco, Kolts, et al., 1977. Emission spectra in a neon matrix Goodman and Brus, 1976 give ω"e = 247 Goodman and Brus, 1976, ω"ex"e = 10.2 Goodman and Brus, 1976. |
| 7 | ESR sp. 10 |
| 8 | From Tellinghuisen, Tisone, et al., 1976 after correction for change in the v numbering of the ground state. Extensive ab initio calculations Liskow, Schaefer, et al., 1973 suggested an essentially repulsive potential for X 2Σ; much better agreement with the spectroscopic result is obtained Krauss and Liu, 1976 if, in addition, the contribution to binding from the dispersion interaction is taken into account. |
| 9 | D00(XeF) + I.P.(Xe) - D00(XeF+). |
| 10 | In γ-irradiated solid XeF4 and XeF2 Morton and Falconer, 1963, Eachus and Symons, 1971. |
