Vibrational relaxation of NO~+ (v) in collisions with CH_4: experimental and theoretical studies

摘要

The rate constants for vibrational relaxation of NO~+ (v = 1) and NO~+ (v = 4) in collisions with CH_4 were measured from thermal to 1 eV center of mass collisional energy using a selected ion flow drift tube. These experimental data are interpreted theoretically using the semiclassical (classical path) approach of Billing and the potential energy surface, constructed on the basis of the model of Gislason and Ferguson.
