A model analysis of rotationally inelastic Ar + H${}_2$O scattering in an electric field

Abstract

We develop an analytic model of thermal state-to-state rotationally inelastic collisions of asymmetric-top molecules with closed-shell atoms in electric fields, and apply it to the Ar--H${}_2$O collision system. The predicted cross sections as well as the steric asymmetry of the collisions show at fields up to 150 kV/cm characteristic field-dependent features which can be experimentally tested. Particularly suitable candidates for such tests are the $0_{00}\to 2_{20}$ and $1_{01}\to 2_{21}$ channels, arising from the relaxation of the field-free selection rules due to the hybridization of $J$ states. Averaging over the $M^{\prime }$ product channels is found to largely obliterate the orientation effects brought about by the field.
