Paper Abstract

Resonant four-photon scattering and excited molecules depopulation/rotational diffusion are considered. Scattering pulse is generated due to three ultrashort pulses interacting with molecules. First pulse prepares excited molecules and two coincident probe pulses, which have a delay in time relative to excitation pulse and in resonance with absorption band of excited molecules, control a transient nonlinear susceptibility. High sensitivity of proposed nonlinear optical measurements to orientational motion of excited molecules is shown.
