1IR sp. 5

3Thermochemical value (mass-spectrom.) Colin and Drowart, 1964, corrected for the new value of D00(Te2). Extrapolation of the vibrational levels of the E state Drummond and Barrow, 1952 gives 4.1 ± 0.4 eV.
4There seem to be two components of this band system, possibly owing to strong perturbations.
5In low-temperature nitrogen matrix.
