We pose and solve a new quantum statistical counting problem and develop it fiuther to obtam a theory for intramokmlar vIbratIona couphng. Simple analytlul expresnons are presented for T1 and Tz relautlon rates. The formulas predict. m agreement wth expenments. that tigh energy linewdths are nearly
## 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
