High-Resolution Infrared Spectroscopy and ASAP Analysis of Cyclopentadiene: The Vibrational Modes below 860 cm and the Mode at 961 cm
Luis Bonah, Marie-Aline Martin-Drumel, Olivier Pirali +9
The spectroscopic fingerprints of vibrationally excited states of astronomical molecules are interesting for multiple reasons. They are excellent temperature probes of the correspo…
Evidence for electron spin-torsion coupling in the rotational spectrum of the CHCO radical
Laurent H. Coudert, Olivier Pirali, Marie-Aline Martin-Drumel +4
Open-shell non-rigid molecular systems exhibiting an internal rotation are likely candidates for a coupling between the spin angular momentum of the unpaired electron and the torsi…
PDRs4All XI. Detection of infrared CH and CH rovibrational emission in the Orion Bar and disk d203-506: evidence of chemical pumping
Marion Zannese, Benoît Tabone, Emilie Habart +20
The methylidyne cation (CH) and the methyl cation (CH) are building blocks of organic molecules, yet their coupled formation and excitation mechanisms remain mainly unpro…
Submillimeter-wave spectroscopy of the CHO radical
Jean-Thibaut Spaniol, Olivia Chitarra, Olivier Pirali +2
The methoxy radical, CHO, has long been studied experimentally and theoretically by spectroscopists because it displays a weak Jahn-Teller effect in its electronic ground state…
Unveiling gas phase H2NCO radical: Laboratory rotational spectroscopy and interstellar search toward IRAS 16293-2422
Marie-Aline Martin-Drumel, Audrey Coutens, Jean-Christophe Loison +2
Context. The carbamoyl radical (H2NCO) is believed to play a central role in the ice-grain chemistry of crucial interstellar complex organic molecules as formamide and acetamide. Y…
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…
The Bending of C: Experimentally Probing the -type Doubling and Resonance
Marie-Aline Martin-Drumel, Qiang Zhang, Kirstin D. Doney +7
C, a pure carbon chain molecule that has been identified in different astronomical environments, is considered a good probe of kinetic temperatures through observation of trans…
A rotational and vibrational investigation of phenylpropiolonitrile (CHCN)
Zachary Buchanan, Kin Long Kelvin Lee, Olivia Chitarra +3
The evidence for benzonitrile (CHCN}) in the starless cloud core TMC-1 makes high-resolution studies of other aromatic nitriles and their ring-chain derivatives especially…
Extensive ro-vibrational analysis of deuterated-cyanoacetylene (DCN) from millimeter-wavelengths to the infrared domain
M. Melosso, L. Bizzocchi, A. Adamczyk +12
Cyanoacetylene, the simplest cyanopolyyne, is an abundant interstellar molecule commonly observed in a vast variety of astronomical sources. Despite its importance as a potential t…
First detection of NHD and ND in the interstellar medium
M. Melosso, L. Bizzocchi, O. Sipilä +7
Deuterium fractionation processes in the interstellar medium (ISM) have been shown to be highly efficient in the family of nitrogen hydrides. To date, observations were limited to…
Far-infrared laboratory spectroscopy of aminoacetonitrile and first interstellar detection of its vibrationally excited transitions
M. Melosso, A. Belloche, M. -A. Martin-Drumel +8
Aminoacetonitrile, a molecule detected in the interstellar medium only towards the star-forming region Sagittarius B2 (Sgr B2) thus far, is considered an important prebiotic specie…
Submillimetre and far-infrared spectroscopy of monodeuterated amidogen radical (NHD): improved rest-frequencies for astrophysical observations
Luca Bizzocchi, Mattia Melosso, Barbara Michela Giuliano +6
Observations of ammonia in interstellar environments have revealed high levels of deuteration, and all its D-containing variants, including ND, have been detected in cold prest…
Conformational Landscape of Oxygen-Containing Naphthalene Derivatives
Manuel Goubet, Marie-Aline Martin-Drumel, Florent Réal +2
Polycyclic aromatic compounds (PACs) constitute an important class of molecules found in various environments and are considered important pollutants of the Earth's atmosphere. In…
Searches for Interstellar HCCSH and HCCS
Brett A. McGuire, Christopher N. Shingledecker, Eric R. Willis +14
A long standing problem in astrochemistry is the inability of many current models to account for missing sulfur content. Many relatively simple species that may be good candidates…
Submillimeter spectroscopy and astronomical searches of vinyl mercaptan, CHSH
Marie-Aline Martin-Drumel, Kin Long Kelvin Lee, Arnaud Belloche +8
We have extended the pure rotational investigation of the two isomers syn and anti vinyl mercaptan to the millimeter domain using a frequency-multiplication spectrometer. The speci…
