ti general formula of the probability of vibrational transitions in diatomic molecules is formulated with specific consideration of vibration-vibration energy transfer for nonresonant cases. An application to HZ-H2 collisions shows an excellent agreement of the present formulation with exact quantum

β¦ Synopsis
A classical model for V-R and V-V energy transfer between two dissimilar diatomic molecules is proposed. For the exponential repulsive potentid, in the limit as the rotation of the mplecules goes to zero, the presenr model reduces to the previous resu!ts for V-T and V-V energy transfer. For the hydrogen halides, whose rchxation is gcnerally accepted as being governed by V-R energy transfer, the Pr's prcdictcd by the present theory agree masonably well with the experimental data. In particular, the positive and negtive temperature dependence of the V-VFr's for N2 -HI and Nz -DI are predicted.

This paper analyses the validity of the fist Born approsimation for the study of the vibrational transitions brought about during a collision between two dllltomic molecules. The work shows the importance of the alteration of the mclecular parameters during the collision and the anharmonicity of the
