Light-Scattering Study of the Pretransitional Phenomena in the Isotropic Phase of Cholesteryl Oleyl Carbonate (COC)

Abstract
We have measured the Rayleigh intensity and spectrum of cholesteryl oleyl carbonate (COC) above the isotropic-cholesteric transition. The anomalous temperature dependence of the linewidth which we have discovered is discussed in depth. Our results differ in many respects from the work reported in a recent Letter by Harada and Crooker.
