Abstract

Cross relaxation between colliding molecules has been shown recently to contribute to the resonance broadening of gas spectra even in the low-pressure (impact) limit, owing to the resonance transfer being an actual final state (and not only a virtual intermediate state) of the binary collision. These resonance-transfer terms are expressed here in terms of the intermolecular potential in the fashion of the Anderson-Tsao-Curnutte theory. Conditions are stated (illustrated by examples) under which these terms contribute appreciably to atomic and molecular spectra.
