OPTICAL TEXTURES IN LIQUID CRYSTAL MIXTURES

Transition temperature is of the one of the important characteristics of a Liquid Crystal (LC) which can be measured over temperature range of phases. The phase transition of liquid crystal between various mesomorphic forms occurs at a thermodynamically defined temperature as the liquid crystal undergoes a change in internal order at the point of phase transition. In this paper, we studied the properties of light as it propagates through a sample of nematic liquid crystal. We studied scattering of light at various temperatures through nematic liquid crystals using Fabry ? Perot Scattering Studies (FPSS). These results are analyzed with the help Polarizing Microscopy Spectroscopic (PMS).These studies have confirmed the mesophase transition temperatures which were found using Polarizing Microscopy study (PMS).
