Abstract

The polarization dependence of hyper-Rayleigh second harmonic light scattering (SHS) and hyper-Raman light scattering (HRS) measured for liquid CDCl₃ show the effect of long-range correlation of molecular orientation and vibration. HRS from the ν₁, ν₄, and ν₅ vibration modes is polarized transverse to the scattering wavevector, whereas HRS from the ν₂, ν₃, and ν₆ vibration modes and SHS from the ν₀ orientation mode all show longitudinal polarization. The transverse polarized HRS is accounted for by long range vibration correlation due to dipole–dipole interaction for molecules at 20–400 nm separation. Longitudinal SHS and HRS are due to the combined effect of long range dipole–dipole orientation correlation and the increment in the molecular first hyperpolarizability induced by short range intermolecular interactions.
