Abstract :
The time-resolved optical Kerr responses of several simple molecular liquids are probed with 65-fs laser pulses. Four dynamically distinct responses associated with the nonlinear susceptibility are observed in every liquid that possesses a permanent anisotropic polarizability. A simple model that specifically includes inertial effects provides an excellent description of the entire temporal profile of the Kerr signal of each liquid investigated. The role of coherent-coupling effects in the interpretation of optical Kerr data is outlined both experimentally and theoretically
