Ab initio quantum scattering calculations and a new potential energy surface for the HCl
(X1Σ+)–O2 (⁠ X3Σg−⁠) system: Collision-induced line shape parameters for O2-perturbed …

Information about molecular collisions is encoded in the shapes of collision-perturbed
molecular resonances. This connection between molecular interactions and line shapes is …

We report fully quantum calculations of the collisional perturbation of a molecular line for a
system that is relevant for Earth's atmosphere. We consider the N 2-perturbed pure rotational …

Doppler-broadened absorption and dispersion spectra of the Q (1) line in the first overtone
band of H 2 were recorded together with a comb-locked cavity-enhanced spectroscopy …

Context. The collisional (de-) excitation of H 2 by He plays an important role in the thermal
balance and chemistry of various astro-physical environments, making accurate rate …

This work theoretically studied the spectral line shape of H 2 O perturbed by Ar in the
temperature range of 20–300 K for the pure rotational lines below 360 cm− 1, as well as …
