DCCCHO
Propynal, deuterated at C3
Species tag 055515
Version1*
Date of EntryMar. 2018
ContributorH. S. P. Müller

The microwave frequencies have been reported by
(1) C. C. Costain and R. J. Morton, 1959, J. Chem. Phys. 31, 389.
The millimeter wave frequencies have been reported by
(2) M. Takami, 1980, J. Mol. Spectrosc. 80, 301.
Some transitions from (2) with larger residuals were omitted from the fit. The entry should be sufficient for identifying the isotopolog in dark clouds. Predictions with uncertainties larger than 0.3 MHz should be viewed with caution.
The dipole moment was assumed to agree with that of the main species, see e054510.cat.
