1 Barrow and Rowlinson, 1954 give 58809.6 which does not fit with their observed (or calculated) nu00.
2omegaexe = 2.9 - 5E-5(v+1/2)5 (valid for v' leq 17).
3Small Lambda-type doubling. Several perturbations, probably by a 1Pi (or 1Delta) state Lagerqvist, Nilsson, et al., 1959.
4RKR potential functions Nair, Singh, et al., 1965.
5Franck-Condon factors, relative band intensities, variation of electronic transition moment with r Dube and Rai, 1971.
6The observed 118Sn and 116Sn isotope shifts for the 0-1 band Lagerqvist, Nilsson, et al., 1959 seem to confirm the v' numbering. See, however, Smith and Meyer, 1968 who suggest that v' be increased by 1.

8 Torring, 1967 gives rotational constants for seven isotopes. Dipole moment from Stark effect of rotation spectrum muel(v=0) = 4.32 D Mahanti, 1931. Zeeman effect Honerjager and Tischer, 1973, gJ(v=0) = -0.1463.
9Thermochemical value Colin, Drowart, et al., 1965. Extrapolation of the E-X v"=0 progression gives a dissociation limit at 45770 cm-1 Barrow and Rowlinson, 1954; if it corresponds to 3P1 + 3P1 [see Barrow, 1970] a dissociation energy of 5.45 eV would follow.
10Both v=1 and v=2 are extensively perturbed.
11In argon and nitrogen matrices.
