The experimental lines are from
(1) K. Georgiou, H. W. Kroto, and B. M. Landsberg, 1979, J. Mol. Spectrosc. 77, 365.
Some higher order centrifugal distortion constants were estimated by
(2) H. S. P. Müller, 2022, unpublished.
Calculations of transition frequencies with Ka = 0 and 1 may be reliable to 53 GHz, possibly to 120 GHz. Transition frequencies with Ka larger than 1 should be viewed with increasing caution. The calculation were limited to Ka = 5.
There are no non-trivial spin-statical weight ratios in HDC2S.
The dipole moment of the main isotopolog was determined by
(3) M. Winnewisser and E. Schäfer, 1980, Z. Naturforsch. A 35, 483.
