INFLUENCE OF ROTATIONAL DYNAMICS ON COLLISIONAL DEPOLARIZATION AND QUENCHING OF MOLECULAR LUMINESCENCE IN GAS PHASE
Theoretical expressions describing the collisional depolarization of the luminescence of polyatomic molecules in gas phase are obtained with account of the donor molecule rotation in a dynamic regime of the excitation quenching. Effects of the quenching cross-section dependence on the rotation rate are examined by numerical calculations for a number of models. It is shown that the decay of luminescence anisotropy substantially intensifies with a degree of the rotational modulation of the energy transfer.
