Abstract: The physical properties of the mixture of two non-mesomorphic compounds which give considerable insight into the mesomorphic state of the compound, have been studied. The mesomorphic states of mixture of cholesterol (non-mesomorphic compound) and tetradecanol (non-mesomorphic compound) have been studied which give twisted nematic phase or cholestric phase and have wide applications in optical devices or display devices. The thermal behaviour of ultrasonic velocity, specific volume, adiabatic compressibility and molar compressibility in the mixture at phase transition and their interpretation have been investigated. The results using Fabry Perrot Scattering Studies [FPSS] are also presented.
