Theoretical probabilities of V-V energy transfer: CO with isotopes of N 2 and deactivation of laser-excited SO 2

Abstract

Modified equations of the SSH method have been used to calculate the vibrational energy exchange of two systems: (1) the probabilities of energy transfer between CO and isotopes of N 2 below 300 K and (2) the probabilities and rate constants for the deactivation of infrared laser excited SO 2 at 298 K. The effect of the intermolecular interaction parameter α, the collision cross reference factor ( r 1/σ), the transition matrix elements, attractive forces, and interactions of the type dipole-dipole and dipole-quadrupole have been studied to observe their influence in those systems. The proposed models reproduce the known experimental results.
