Deuterium enhancement of monodeuterated species has been recognized for more than 30 years as a result of chemical fractionation that results from the difference in zero-point energies of deuterated and hydrogenated molecules. The key reaction is the deuteron exchange in the reaction between HD, the reservoir of deuterium in dark interstellar clouds, and the molecular ion, leading to the production of H2D+ molecule, and the low temperature in dark interstellar clouds favours this production… Expand

Observations of molecular D/H ratios in the interstellar medium are used to probe the physical conditions, such as temperature, ionization fraction and the importance of gas–grain reactions. In cold,Expand
Ortho-H2 and the age of prestellar cores
Prestellar cores form from the contraction of cold gas and dust material in dark clouds before they collapse to form protostars. Several concurrent theories exist to describe this contraction butExpand
The H+ + H2 reaction
plays a crucial role in Astrophysics, taking part in the early chemistry responsible for the formation of the stars. It is also one of the most abundant ionic species in hydrogen plasmas. TheExpand

It is shown that the ground-state ortho-H2D+ transition is the best, if not the only, tracer of the disk-plane gas, and that it may also reveal the matter in the dark halos of external galaxies, if it is hidden in cold, dense and small clouds, as several theories predict. Expand
The Chemical Structure of Young High-mass Star-forming Clumps. I. Deuteration
The chemical structure of high-mass star nurseries is important for a general understanding of star formation. Deuteration is a key chemical process in the earliest stages of star formation becauseExpand
Reactive molecular dynamics simulation for isotope-exchange reactions in H/D systems: ReaxFFHD development.
There remains a preference for D in the produced molecular ions, which is related to the lower zero-point energy of the D-enriched species, showing the isotope effects at the heart of the ReaxFFHD potential. Expand
Depletion and low gas temperature in the L183 (= L134N) prestellar core: the N2H + - N2D + tool ⋆
Context. The study of pre-stellar cores (PSCs) suffers from a lack of undepleted species to trace the gas physical properties in their very dense inner parts. Aims. We want to carry out detailedExpand
Atomic and Molecular Aspects of Astronomical Spectra
In the first section we present the atomic part where a C2+ atomic target was prepared and used to generate theoretical data to investigate recombination lines arising from electron-ion collisions inExpand
Using H3+ and H2D+ as probes of star-forming regions
This paper reviews how observations of H3+ and H2D+ species and of heavier ions can be used to derive chemical and kinematic properties of nearby pre-stellar cores and the cosmic ray ionization rate towards more distant regions of high-mass star formation. Expand
Far-Infrared detection of H2D+ toward Sgr B2
We report on the first far-IR detection of H2D+, using the Infrared Space Observatory, in the line of sight toward Sgr B2 in the Galactic center. The transition at ? = 126.853 ?m connecting theExpand


Multiply-deuterated species in prestellar cores.
We have studied the ortho, para, and, in the case of D + , meta forms of the multiply-deuterated isotopes of H + , under physical conditions believed to be appropriate to pre-protostellar cores. AsExpand

Deuterium fractionation mechanisms in interstellar clouds
The theory of the fractionation of deuterated molecules is extended to include reactions with atomic deuterium. With the recognition that dissociative recombination of H/sup +//sub 3/ is not rapid,Expand
