A theory of vlbratxonal redlstributlon has been developed by applying the adiabatic approxunatlon to the separatron of tugh-frequency modes of vlbratlon from low-frequency modes of vibration and molecular rotatron of the molecule, using an anharmotuc potential function

For simple models of the relaxation of highly vibrationally excited molecules the average energy transferred per collision <At} i for molecules with initial energy e, is a significant quantity. For more realistic models (Ae)i is generalized to a quantity [Aqe], which is not strictly an average. We d
## Vlbrational-rotatlonal couphng, due to the fact that the center of interaction IS displaced from the center of mass in a heteronuclear diitomrc molecule, provides a mechanism for nonradiatwe vibrational relazxation of diitomic impurities in matrlces. A theoretical expresaon for the rate constan
The infrved vibration transition ~2 of NH3 isolated in a nitrogen matrix at 8'K is excited by the R(L0) and R(12) lines of the OO?l-10'0 transition of a Q-switched CO2 laser. When the continuous wave CO\* laser, used as a probe, is at the s3me frequency as the pump, a short exponential decay of tran
