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

โฆ Synopsis
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 level. We propose that the perturbing levels are 5* in the case of I 2 and 5* I, in the case of lj. The coupling constant k, 155 has been determined to be I .4 cm-'.
