A theor. treatment of time-resolved CARS and CSRS is given that includes mol. rotation during the time interval between the excitation and probing light pulses. A mol. response function tensor was found that accounts for the vibrational relaxation and the rotational diffusion of the mols. The ensemble av. of this response function with an arbitrary set of polarization conditions for the light pulses yields a sum of 3 terms. Each term is the product of a polarization factor Pl and a mol. rotational relaxation function Ml. New polarization conditions are proposed that permit to measure each of these 3 terms sep.
