Context. The global context of making numerous data produced by researchers available
requires collecting and organising the data, assigning meaningful metadata, and presenting …

The HCO+ and DCO+ molecules are commonly used as tracers in the interstellar medium.
Therefore, accurate rotational rate coefficients of these systems with He and H2 are crucial …

The rotational dynamics of isocyanogen (CNCN) is studied for its collision with para (p-) and
ortho (o-) hydrogen (H 2) in the temperature range of 1–100 K. These temperatures …

We present a new method taking explicitly into account the coupling between rotation and
bending of a nonlinear triatomic molecule colliding with an atom. This approach based on a …

Vibrationally excited levels of the H2O molecule are currently detected in various
environments of the interstellar medium (ISM), and collisional data for H2O, including …

We extend our recent theoretical work on the bending relaxation of H2O in collisions with H2
by including the three water modes of vibration coupled with rotation, as well as the rotation …

We present a close coupling study of the bending relaxation of H 2 O by collision with He,
taking explicitly into account the bending–rotation coupling within the rigid-bender close …

The quantum dynamics of rotational transitions of the diisocyanogen (CNNC) molecule
undergoing collision with the helium (He) atom occurring in the interstellar medium (ISM) …

The recent interstellar detections of ArH+ and HeH+ have increased the interest in noble
molecules. In this work, we develop potential energy surfaces (PESs) at a high level of …

Context. An accurate analysis of the physical-chemical conditions in the regions of the
interstellar medium in which C 3 is observed requires knowing the collisional rate …
