Spectral features of hyper-Rayleigh scattering in chloroform-d

چکیده
Ž . Measurements of hyper-Rayleigh scattering HRS in chloroform-d indicate that interaction induced contributions account for more than half of the scattered intensity from the liquid phase. The effective hyperpolarizability obtained from 2 2 : the entire liquid HRS spectrum in the VV polarization geometry is b s15.7"0.6 au. The unimolecular VV 2 2 : hyperpolarizabilities obtained from the Lorentzian components of the HRS spectrum are b s10.2"0.7 au and VV b s10.8"0.5 au. This value for b differs substantially from that previously inferred from electric field induced second 5 5 Ž . harmonic generation EFISH measurements, calling into question previous HRS results calibrated using chloroform as a standard. q 1998 Elsevier Science B.V.

Spectral measurements of hyper-Rayleigh light scattering
An apparatus is described for the measurement of second-order nonlinear optical properties via hyper-Rayleigh scattering with 1 cm spectral resolution of the scattered light. The setup allows a complete investigation of the polarization dependence of the second-harmonic scattered light. The combination of good spectral resolution, polarization analysis, and high sensitivity allows the determina...
متن کاملAccurate hyper-Rayleigh scattering polarization measurements.
Apparatus and methods are described for measurement of the polarization dependence of hyper-Rayleigh scattering near 90° scattering angle with 0.1% accuracy for all four configurations where the incident and scattered light is linear polarized either parallel or perpendicular to the scattering plane. Measurements are made with large collection aperture and extrapolated to zero collection numeri...
متن کاملNonresonant 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...
متن کاملPolar domain fluctuations in doped liquid nitrobenzene.
Improved spectral measurements of the narrow spike in the high resolution hyper-Rayleigh light scattering spectrum for deuterated liquid nitrobenzene (C(6)D(5)NO(2)) doped with triflic acid (CF(3)SO(3)H) determined that the reorientation time for the dopant-induced polar domains is 2.9 micros in the dilute limit. Two models based on ions dissolved in nitrobenzene fit the measured spectral broad...
متن کاملSpontaneous, 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...
