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 ammonia (NH$_2$D, NHD$_2$, ND$_3$) and imidogen radical (ND) isotopologues. We want to explore the high frequency windows offered by the \emph{Herschel Space Observatory} to search for deuterated forms of amidogen radical NH$_2$ and to compare the observations against the predictions of our comprehensive gas-grain… Expand

Deuterium fractionation of nitrogen hydrides: detections of NHD and ND2
Although ammonia is an abundant molecule commonly observed towards the dense interstellar medium, it has not yet been established whether its main formation route is from gas-phase ion-moleculeExpand
First detection of doubly deuterated methyl acetylene (CHD2CCH and CH2DCCD)★.
The first detection in space of the two doubly deuterated isotopologues of methyl acetylene is reported, which points to gas-phase chemical reactions, rather than grain-surface processes, as responsible for the formation and deuterium fractionation of CH3CCH in L483. Expand
High resolution FTIR study of the ν5, ν6, and ν9 fundamental bands of CH2D37Cl
Abstract The first high-resolution infrared spectra of CH2D37Cl have been investigated in the region 650–1100 cm−1 where the lowest fundamental bands ν5 (826.2626 cm−1), ν6 (708.4307 cm−1), and ν9Expand
Improved centrifugal and hyperfine analysis of ND2H and NH2D and its application to the spectral line survey of L1544
Abstract Quantifying molecular abundances of astrochemical species is a key step towards the understanding of the chemistry occurring in the interstellar medium. This process requires a profoundExpand
Space and laboratory observation of the deuterated cyanomethyl radical HDCCN
Our observations of TMC-1 with the Yebes 40 m radio telescope in the 31.0-50.3 GHz range allowed us to detect a group of unidentified lines, showing a complex line pattern indicative of an open-shellExpand
First sample of N2H+ nitrogen isotopic ratio measurements in low-mass protostars
Context. The nitrogen isotopic ratio is considered an important diagnostic tool of the star formation process, and $N_2H^+$ is particularly important because it is directly linked to molecularExpand

Atomic deuterium/hydrogen in the Galaxy
An accurate value of the D/H ratio in the local interstellar medium (LISM) and a better understanding of the D/H variations with position in the Galactic disk and halo are vitally important questionsExpand
Deuterium hyperfine splittings in the rotational spectrum of NH2D as revealed by Lamb-dip spectroscopy
Abstract In the context of radio-astronomical observations, laboratory experiments constitute a cornerstone in the interpretation of rich line surveys due to the concomitant presence of numerousExpand
Submillimeter and Far-infrared Spectroscopy of Monodeuterated Amidogen Radical (NHD): Improved Rest Frequencies for Astrophysical Observations
Observations of ammonia in interstellar environments have revealed high levels of deuteration, and all its D-containing variants, including ND$_3$, have been detected in cold prestellar cores andExpand
Modeling deuterium chemistry in starless cores: full scrambling versus proton hop
We constructed two new models for deuterium and spin-state chemistry for the purpose of modeling the low-temperature environment prevailing in starless and pre-stellar cores. The fundamentalExpand
The pure rotational spectrum of 15ND2 observed by millimetre and submillimetre-wave spectroscopy.
Abstract The pure rotational spectrum of the amidogen radical 15ND2 has been observed between 264 and 1051 GHz with a source-modulation millimetre- and submillimetre-wave spectrometer. A total of 346Expand
The rotational spectrum of 15ND. Isotopic-independent Dunham-type analysis of the imidogen radical.
The rotational spectrum of 15ND in its ground electronic X3Σ- state has been observed for the first time and the Born-Oppenheimer equilibrium bond distance for the imidogen radical has been calculated and zero-point energies have been derived for all the isotopologues. Expand
Why does ammonia not freeze out in the center of pre-stellar cores?
We carried out a parameter-space exploration of the ammonia abundance in the pre-stellar core L1544, where it has been observed to increase toward the center of the core with no signs of freeze-outExpand
