Depolarization and angular dependences of n-harmonic scattered light in statistically inhomogeneous media

A semi-classical theory of multi-harmonic scattering of intense light on individual molecules, as well as on statistical fluctuations of molecular fields in near ordering areas of isotropic bodies, is proposed. Vertical and horizontal intensity components and depolarisation ratios of n-harmonics are discussed as functions of the scattering angle, and relations between them are derived. The even harmonics are shown to be sensitive to molecular symmetry (natural, or induced by molecular field fluctuations) whereas odd harmonics can be scattered from any substances, molecular or atomic.
