1IR sp. 5
2Microwave sp. 6
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.
6muel(v=0)= 1.06 D Hoeft, Lovas, et al., 1970 from Stark effect of microwave spectrum Hoeft, Lovas, et al., 1970; hyperfine structure of 73Ge Tiemann, Hoeft, et al., 1971. See also Hoeft, Lovas, et al., 1970, 2.
