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 nature of the initial energy distrkwtion. fkutcration causes a procounted increase in the relaxation. The exact conditions necessary to have a given

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\_
Rotationally resolved dispersed fluorescence spectra from the 6' level of benzene have been used to probe intramolecular vibrational energy redistribution in the ground electronic state. The level I2 (Evib= 1986 cm-') and 1, (I?",,=2979 cm-') are observed to be each coupled to a single close-lying l
