Vibrational distribution of multiatomic molecules
Abstract
A quasistationary vibrational distribution in strongly excited multiatomic molecules due to vibrational exchange (distribution with plateau) is considered. Anharmonic coupling of vibrational modes makes it impossible to consider them in isolation, so that it is question of a distribution in the space of vibrational mode numbers. A formula is derived for the vibrational quantum flux, describing relaxation of the distribution with plateau. CO2 and NO2 molecules are considered as examples.
