HCCD
Acetylene, ethyne, monodeuterated species
Species tag 027511
Version1*
Date of EntryJan. 2008
ContributorH. S. P. Müller

Pure rotational were reported in
(1) G. Cazzoli, C. Puzzarini, L. Fusina, and F. Tamassia, 2008, J. Mol. Spectrosc. 247, 115.
The lowest energy transitions lie in unfavorable frequency regions. Nevertheless, it is conceivable that this species may be detected by radioastronomical means.
Predictions should be reliable up to at least 1.5 THz.
The dipole moment was derived from experiments described in
(2) K. Matsumura, T. Tanaka, Y. Endo, S. Saito, and E. Hirota, 1980, J. Chem. Phys. 84, 1793.
