title: Nonlocal hyper-Rayleigh scattering from liquid nitrobenzene.
abstract: Hyper-Rayleigh scattering (HRS) from liquid nitrobenzene was measured for several combinations of linear polarized incident and scattered light, for a range of scattering angles near 90 degrees . The observations show that the HRS intensity is dominated by the polar transverse collective mode contribution, and support a model where the long range dipole-dipole orientation correlations in a polar liquid result in coherent HRS from beta((1)), the vector part of the molecular first hyperpolarizability beta, whereas HRS from the octupolar part beta((3)) remains local and incoherent.
