Non-linear optical channels of the polarizability induction in a pair of interacting molecules
Abstract
Intermolecular interactions give rise to the incremental polarizabilities in molecular ensembles that triggers the Raman vibrational transitions forbidden by selection rules for isolated molecules. By using the diagrammatic technique, a new channel of the long-range binary polarizability induction is established, for which the outer field and the electric field of a molecule non-linearly polarize the other particle. An account for this channel is found to be crucial for a successful quantitative interpretation of the СО2 ν3 Raman band induced by the СО2-СО2 and СО2-Ar collisions.
