Notes

1Λ-type doubling Δνef = +0.0010J(J+1).
2From bandheads, taking into account head-origin separations.
3Slight modification of the analysis of the 1-1 band in Woods, 1943.
40-0 sequence only. Constants recalculated assuming that the lower state is X 1Σ+.
5From a partial rotational analysis, assuming that the lower state is X 1Σ+.
6Microwave sp. 8
7Thermochemical value (mass.spectrom.) Hildenbrand, 1968. See also Kent, McDonald, et al., 1966.
8μel(v=0) = 5.77 D. Values for eqQ(Cu) in Hoeft, Lovas, et al., 1970, magnetic constants from Zeeman effect measurements in Honerjager and Tischer, 1974.
