Some experimental Brillouin scattering measurements have been performed on binary mixtures composed by a liquid crystal immersed in a non polar solvent. The experimental compressibility has been fitted using a theoretical approach based on a hard-core model whose reliability has been successfully checked for many binary mixtures of molecular liquids. In this article we generalize this apparently naïve approach to the case where the molecular shape of one of two involved species is elongated. The agreement with experimental results seems to support our leading idea that the compressibility behaviour is mainly driven just by excluded volume interactions.

Abstract
Some experimental Brillouin scattering measurements have been performed on binary mixtures composed by a liquid crystal immersed in a non polar solvent. The experimental compressibility has been fitted using a theoretical approach based on a hard-core model whose reliability has been successfully checked for many binary mixtures of molecular liquids. In this article we generalize this apparently naïve approach to the case where the molecular shape of one of two involved species is elongated. The agreement with experimental results seems to support our leading idea that the compressibility behaviour is mainly driven just by excluded volume interactions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
