Preliminary results arc reported of a Monte Carlo trajectory study of intramolecular vibrational ener\_w relaxation in a model of benzene. Very little relaxation 1s found to occur on d picosecond timeswle. The rate of intramolecular wbrational energy relaxation appears to be dependent upon the natur

A simple dynamical model is used to calculate the overtone spectra of CH and CD stretch vibrations of C6H6 and C6D6 in both vapour and liquid phases. The quantized version of this model describes the normal-mode character of the first excited states. A semiclassical version describes the local-mode
The second CH stretch overtone of benzene has been studied both experimentally and theoretically. A recent high-resolution opto-thermal experiment showed that the overtone spectrum consists of several absorption bands located in the region between 8730 and 8875 cm-'. In this work, we investigate pos
The energy decay of CH-stretchmg modes is measured for the molecules C6H6, C6HsC1. C&sCHB, C&&(CI-Ks j2, and CsNHs in the liquid phase. The observed lifetimes vary between f and 2 ps. In the theoretical analysis, three fast decay mechanisms are discussed\_
