Laboratory rotational spectroscopy leads to the first interstellar detection of singly deuterated methyl mercaptan (CHDSH)
Hayley A. Bunn, Silvia Spezzano, Laurent H. Coudert +8
We report an extensive rotational spectroscopic analysis of singly deuterated methyl mercaptan (CHDSH) using both millimeter and far-infrared synchrotron spectra to achieve a…
Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk
Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53
Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
Millimetre and sub-millimetre spectroscopy of doubly deuterated acetaldehyde (CHD2CHO) and first detection towards IRAS 16293-2422
J. Ferrer Asensio, S. Spezzano, L. H. Coudert +4
The abundances of deuterated molecules with respect to their main isotopologue counterparts have been determined to be orders of magnitude higher than expected from the cosmic abun…
Successive deuteration in low-mass star-forming regions: the case of D-methanol (CHDOH) in IRAS 16293-2422
Maria N. Drozdovskaya, Laurent H. Coudert, Laurent Margulès +3
Accurate quantification of the column density of di-deuterated methanol is a key missing puzzle piece in the otherwise thoroughly constrained family of D-bearing methanol in the de…
The NHD hyperfine structure revealed by astrophysical observations
F. Daniel, L. H. Coudert, A. Punanova +8
The 1-1 lines of ortho and para--NHD (o/p-NHD), respectively at 86 and 110 GHz, are commonly observed to provide constraints on the deuterium fractionation in…
Detection of 15NH2D in dense cores: A new tool for measuring the 14N/15N ratio in the cold ISM
Maryvonne Gerin, Nuria Marcelino, Nicolas Biver +5
Ammonia is one of the best tracers of cold dense cores. It is also a minor constituent of interstellar ices and, as such, one of the important nitrogen reservoirs in the protosolar…
