Abstract

The effect of rotational predissociation on the polarization response of an ensemble of photofragments is investigated within the framework of the model with free scatter of fragments for the most general case when both original molecules and fragments are asymmetric rotators. Photoinduced decomposition reactions with single- and two-photon excitation of fragment fluorescence are analyzed. Second- and third-order orientational correlation functions determining the polarization degree of fragment fluorescence are calculated. The behavior of these correlation functions depending on the shape of original molecules and fragments, directions of dipole moments, and characteristic times of the process are analyzed.
