Hyper-Rayleigh scattering from correlated molecules.

Polarization and angle dependence for hyper-Rayleigh scattering from local and nonlocal modes of isotropic fluids

Collective modes of molecular motion result in long-range correlations between molecules. Orientation correlations between the molecules of an isotropic fluid owing to polar collective modes result in hyper-Rayleigh scattering with distinctive polarization and angle dependence. The polarization and angle dependence for hyper-Rayleigh scattering from polar transverse-optical and longitudinal-opt...

Spontaneous, stimulated, coherent and incoherent nonlinear wave mixing and Hyper-Rayleigh scattering; a unified quantum-field description

By combining a quantum treatment of the radiation field with a superoperator formalism we present compact expressions for a broad variety of coherent and incoherent nonlinear optical signals. Spontaneous signals are classified according to the molecular coherence range: homodyne detected signals result from long range two particle coherence whereas Rayleigh and hyper-Rayleigh scattering are sho...

Hyper-Rayleigh scattering of centrosymmetric molecules in solution

Computational study of the Rayleigh light scattering properties of atmospheric pre-nucleation clusters.

The Rayleigh and hyper Rayleigh scattering properties of the binary (H2SO4)(H2O)n and ternary (H2SO4)(NH3)(H2O)n clusters are investigated using a quantum mechanical response theory approach. The molecular Rayleigh scattering intensities are expressed using the dipole polarizability α and hyperpolarizability β tensors. Using density functional theory, we elucidate the effect of cluster morpholo...

Nonresonant hyper-Raman and hyper-Rayleigh scattering in benzene and pyridine

Nonresonant hyper-Raman and hyper-Rayleigh spectra excited at 1064 nm are reported for neat benzene and pyridine. The theory of Herzberg-Teller vibronic coupling in nonresonant and preresonant hyper-Raman scattering is developed. Nonresonant hyper-Raman scattering is shown to be vibronically induced by modes that efficiently couple strongly allowed onephoton and two-photon transitions. A weak a...
