Forced Rayleigh Scattering from Lipid-Water Smectic Phases

Thermal diffusion forced Rayleigh scattering setup optimized for aqueous mixtures.

We developed a thermal diffusion forced Rayleigh scattering (TDFRS) setup operating at a writing wavelength of 980 nm, which corresponds to an absorption band of water with an absorption coefficient of approximately 0.5 cm(-1). Therefore, aqueous mixtures require no dye to convert the light into heat energy. Especially for aqueous system with a complex phase behavior such as surfactant systems,...

Rayleigh scattering from pivalic acid

2014 Both the polarized and depolarized spectra of Rayleigh scattering from pivalic acid have been measured with high precision. The relaxation time for molecular reorientation and the energy of activation are deduced directly from these measurements for both the liquid and plastic phases of the crystal.

Induced Smectic Phases II. Influence of the Amino Substituent on the Induction of Smectic Phases *

The diagrams of state have been studied for some liquid crystal mixtures which show the induction of smectic phases. Each of the systems studied contains one component with an amino group which influences the polarity and the electron donor property of the molecules. The discussion of the diagrams of state, of the thickness of the smectic layers and of the colours of the mixtures, which indicat...
