“…Actually, this is not surprising. It is well known that the light scattering spectrum of viscous liquids is often better described by a three variable hydrodynamic theory [21,22]. However, such three variable theories contain more adjustable parameters than we can hope to determine with the present experiments, even if we ignore the complexities introduced by the fact that COC consists of chiral molecules.…”

We report a light scattering study in the isotropic phase of a blue phaseforming fluid (cholesteryl-oleylcarbonate). An analysis of the intensity correlation function of the depolarized scattered light indicates that a two variable theory is not adequate to describe the intensity autocorrelation function. Our data are well-described by a stretched exponential decay of the collective orientational fluctuation. Such behaviour is usually observed in the vicinity of a glass transition. In addition we report measurements of the refractive index in the vicinity of the isotropicblue phase transition.

A simple optical low-temperature icing cell was fabricated to obtain the in situ Raman spectra of ice layers forming on metallic substrates. The icing cell is optically coupled to a micro Raman multi-channel spectrometer. The Raman spectra of the initial ice layers show characteristics of a disordered phase resembling low-density amorphous ice. The crystalline phase develops gradually as the thickness of the ice layer increases. The disorder in the initial ice layer may be caused primarily by the rapid thermal cooling, and appears to be independent of the type of metal substrate.
