✦ Synopsis

Vibration-vibration (V-V) exchange rate constants in nitrogen have been calculated using the integral quasiclassical representation method over a wide temperature range. Four different model intermolecular potentials arc used. Comparison with experimental data and with calculations using other semiclassical methods show satisfactory agreement. A dependence ofthe parameter S,, on the vibrational level n was found which accounts for the discrepancy between the experimental data for S,,. The hmited applicability of the conventional parameterization for the V-V exchange rates through Q,,and 6," for near-resonant processes is shown.

The collisional deactivation of HgBr (B %) by He, Ar and Xe has been studied using quasiclassical trajectory calculations. HgBr was initially vibrationally excited in v= 52. The transition probabilities for He and Ar show a double exponential behaviour, while for Xe they are well described by the ad
