The Leiden Atomic and Molecular Database (LAMDA) collects spectroscopic information
and collisional rate coefficients for molecules, atoms, and ions of astrophysical and …

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 …

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 …

The Born–Oppenheimer potential energy surface (PES) has come a long way since its
introduction in the 1920s, both conceptually and in predictive power for practical …

ABSTRACT Hydronium (H3O+) was first detected in 1986 in interstellar molecular clouds. It
was reported in many Galactic diffuse and dense regions, as well as in extragalactic …

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 …

Rotational excitation of interstellar PN molecules induced by collisions with H 2 is
investigated. We present the first ab initio four-dimensional potential energy surface (PES) …

The CO2–N2 complex is formed from two key components of Earth's atmosphere, and as
such, has received some attention from both experimental and theoretical studies. On the …
