Brillouin scattering of light in a cholesteric liquid crystal

摘要

Brillouin scattering was used to study the hypersonic properties of cholesteryl palmitate in the liquid crystalndash;liquid phase transition region. Contrary to the results of similar measurements by Durand and Rao, no anomalous change in either the velocity or the attenuation of the hypersonic waves was observed at the transition.
