Notes

1Charge-transfer transition from a largely ionic upper state (+XeO-) to the largely atomic ground state; see Golde and Thrush, 1974. In argon matrix absorption at 44040 cm-1 Ault and Andrews, 1976.
2Broad emission continuum with maximum at 42000 cm-1, in discharges through Xe + trace of O2 and in chemiluminescence of Xe (3P2) + N2O.
3Narrow band group at 34300 cm-1 in discharges through Xe + O2. Laser excitation produces a broad emission band at 34500 cm-1 in solid argon.
4Te relative to Xe(1S) + O(3P2).
5Observed in emission from electron-beam excited high density Xe + O2 mixtures Lorents and Huestis, 1975 and as laser-excited fluorescence in rare gas matrices Goodman, Tully, et al., 1977.
6The b state vibrational numbering Lorents and Huestis, 1975 is uncertain; according to Goodman, Tully, et al., 1977 it may have to be increased by +1.
7Lifetime tau(v=0,1) ~ 50 mus Tisone, 1974; Aleksandrov, Vinogradov, et al., 1976 suggest the much shorter value tau ~ 0.1 mus Aleksandrov, Vinogradov, et al., 1976.
8Observed in an ozonizer-type discharge through Xe(~ 1 atm) + traces of O2 Cooper, Cobb, et al., 1961; partially resolved rotational structure. Laser-excited fluorescence in rare gas matrices Goodman, Tully, et al., 1977. Laser oscillation observed using electron-beam excitation of high-pressure Xe containing small amounts of O2 Powell, Murray, et al., 1974, Basov, Babeiko, et al., 1976.
9The a state vibrational numbering Cooper, Cobb, et al., 1961 may have to be raised by +3 units; an unambiguous numbering has not been established in spite of the availability of Xe18O data in solid argon Goodman, Tully, et al., 1977.
10Narrow emission peak; in solid argon and neon at 31940 and 32670 cm-1, respectively.
