The J = 1 – 0 transition was taken from
(1) S. Civis, A. Walters, M. Yu. Tretyakov, and M. Bogey, 1998, J. Chem. Phys., 108, 8369
. Rovibrational transitions were taken from
(2) M. Elhanine, R. Farrenq, G. Guelachvili, and M. Morillon-Capey, 1988, J. Mol. Spectrosc., 129, 240
Predictions with J > 10 should be viewed with some caution; lower-J predictions may be fairly reliable if and only if ion drift effects had negligible effects on the infrared data.
It is worthwhile mentioning that the infrared data in (2) predicted the pure rotational transition better than did the original measurements. However, a combined fit of SH data together with SD infrared data yield peculiar sets of spectroscopic parameters indicative of small, but non-negligible inconsistencies in the data sets. Together with larger inconsistencies in the SD pure rotational data set this prevents a meaningful SD entry from being generated.
The ab initio dipole moment was taken from
(3) J. Senekowitsch, H.-J. Werner, P. J. Rosmus, and E.-A. Reinsch, 1988, J. Chem. Phys., 83, 4661.
