Abstract
The origin of subpicosecond decay components found in time-resolved coherent anti-Stokes Raman scattering profile of neat benzene at room temperature under photon polarization condition [Z, X, Z, X] is explained in terms of intermolecular interference effects. Intermolecular interference means interference among rovibrational Raman transitions of benzenes at various sites. The dephasing rate due to the interference is characteristic of the coherent spectroscopy, and is faster than intramolecular vibrational dephasing and reorientational ones at room temperature. © 1992.
