โœฆ Synopsis

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 derive a number of sum rules which show the theoretical significance of quantities [Aqu],

where ai may be some quantity other than c;. For example, if the vibrational relaxation is coupled to reaction, the quantities [ AUK] ; are of importance, xi being the rate constant for reaction of molecules with energy e,.
