Notes

A satisfactory interpretation of the observed bands is still lacking; see Watson and Shambon, 1936, Howell, 1945. Preliminary rotational analysis of two bands by Jacquinot and Lavendy, 1975.

The lower limit is D₀⁰(InS); the upper limit, also based on mass-spectrometric evidence, was estimated by Burns, DeMaria, et al., 1963, Colin and Drowart, 1968.
