✦ Synopsis

Femtosecond optical-heterodyne detected opttcal Kerr effect data for benzene and pyridine liquids are reported. When presented in the frequency-domain representation, these data reveal the presence of low-frequency, Raman-active, intermolecular vibrational modes that previously have not been reported. Considerations suggest that these low-frequency features are associated with predominately overdamped local collective modes involving dimers or higher aggregates.
