Ethynyl, X 2Σ+, deuterium isotopolog
Species tag 026501
Date of EntryApr. 2000
ContributorH. S. P. Müller

The experimental data was taken from
(1) M. Bogey, C. Demuynck, and J. L. Destombes, 1985, Astron. Astrophys. 144, L15; and
(2) J. M. Vrtilek, C. A. Gottlieb, W. D. Langer, P. Thaddeus, and R. D. Wilson 1985, Astrophys. J. 296, L35.
The predictions are probably reliable up to 0.8 THz.
The dipole moment is assumed to be the same as for the main isotopolog, see
