Notes
1 | Observed in a low-pressure discharge through Xe + Cl2 Shuker, 1976. Absorption bands at similar wavelengths are observed in inert gas matrices Ault and Andrews, 1976. |
2 | Based on potential functions chosen for best representation of observed levels and intensities Tellinghuisen, Hoffman, et al., 1976. |
3 | Observed in emission in the reaction of metastable (3P2) Xe atoms with Cl2, NOCl, SOCl2, CCl4 Golde, 1975, Velazco and Setser, 1975 or on electron bombardment of mixtures of Ar + Xe + Cl2 and Xe + HCl or Cl2 at high pressure (of the order of 1 atm) Brau and Ewing, 1975, Tellinghuisen, Hoffman, et al., 1976. Under the latter conditions laser action has been detected Ewing and Brau, 1975, Tellinghuisen, Hoffman, et al., 1976. Observed in absorption and emission in inert gas matrices Ault and Andrews, 1976. |
4 | missing note |
5 | ESR sp. 7 |
6 | Extrapolation of the vibrational levels in X 2![]() |
7 | In argon at 4.2 K. |
