Show moreThe spectral content of hyper-Rayleigh scattering (HRS) was studied with solutions of disperse red-1 (DR1) in acetone at a specific fundamental wavelength. Dephasing can occur when the effective lifetime of the virtual state approaches a two-photon resonance. Experiments were developed that will measure all six observables in HRS by observing the scattering at 45°, continuously varying the phase of the fundamental by rotating a quarter-waveplate, and using another quarter-waveplate with a linear polarizer to analyze the harmonic. These experiments proved the validity of Kleinmann symmetry in near-resonant and far off-resonant regimes.

Show moreMeasurements are reported for the polarization in the ordered phase, and for the tilt susceptibility in the 'disordered' smectic A phase, of mixtures of left- and right-handed enantiomers of TFMHPOBC. The tilt susceptibility was found to exhibit a critical exponent γ=1·20±0·05, and both its magnitude and the polarization were found to be nonmonotonic in enantiomeric excess X of S-TFMHPOBC. Their ratio, however, was found to be approximately constant with X. Several possible explanations are examined.
