The optical Kerr effect of liquid nitrobenzene and chlorobenzene is probed with 65 fs optical pulses at 633 nm. We observe an instantaneous signal contribution which is attributed to the incoherent (dephased) electronic component of the third-order nonlinear susceptibility x"'. Additionally, three non-instantaneous relaxation components are observed in each liquid, including an ultrafast relaxation with an 80 fs lifetime and the previously observed orientational relaxations. A third relaxation component is observed in both liquids with a lifetime on the order of 450 fs. The prevailing diffusional theory of the optical Kerr effect fails to describe the temporal profile of the measured response in both liquids.

Experimental femtosecond OHD-RIKES results of benzene, 1,4-cyclo-hexadiene, 1,5-cyclo-octadiene, benzonitrile, and o-methylbenzonitrile are reported. The goal of these experiments is to elucidate the structure and dynamics of aromatic liquids and to understand the underlying intermolecular forces. T
