Abstract
The purpose of the present communication has been to present the derivation of the vibrational relaxation rate constant for the case in which both phonons and the molecular rotation (three-dimensional) participate in the vibrational relaxation and to study the effect of molecular rotation on the vibration-vibration energy transfer in the condensed phase. The experimental results of vibration-vibration energy transfer between donors, NH and ND, and acceptors, CO and 13CO, have been analyzed.
Keywords: donor (NH, ND); acceptor (CO); oscillators; guest molecules; host lattice
