The determination of physical conditions in interstellar clouds requires reliable estimation of
radiative and collisional data for molecules detected in space. In this work, rate coefficients …

A proper description of the collisional perturbation of the shapes of molecular resonances is
important for remote spectroscopic studies of the terrestrial atmosphere. Of particular …

An updated version of the CO+ CO potential energy surface from [R. Dawes, XG Wang and
T. Carrington, J. Phys. Chem. A 2013, 117, 7612] is presented, that incorporates an …

We present ab initio calculations of the collisional broadening of the R (0) pure rotational
line in CO (at 115 GHz) perturbed by O 2. Our calculations are done in a fully quantum way …

Carbon-chain anions were recently detected in the interstellar medium. These very reactive
species are used as tracers of the physical and chemical conditions in a variety of …

Collisional data for the excitation of NH by H 2 are key to accurately derive the NH
abundance in astrophysical media. We present a new four-dimensional potential energy …

An accurate ground-state intermolecular potential energy surface (PES) was calculated for
the HCS+–H 2 complex. The surface was constructed from 3023 ab initio energies …

Interstellar anions play an important role in astrochemistry as being tracers of the physical
and chemical conditions in cold molecular clouds and circumstellar gas. The local …

A four-dimensional-potential energy surface (4D-PES) of the atmospherically relevant
carbon dioxide–oxygen molecule (CO2–O2) van der Waals complex is mapped using the ab …

The NH and ND radicals are of key importance in the comprehension of nitrogen chemistry
and the enhancement of deuterated molecules in the interstellar medium. Observations by …
