Abstract

Change in the phase of thermotropic liquid crystals occurs at definite phase transition temperatures. A spectroscopic technique using the Fabry-Perot etalon coupled with a spectrometer has been used to determine the mesophase transition temperatures of the liquid crystal-Cholesteryl myristate. New mesophase transitions have been detected and classified at the temperatures of 52 degree(s)C, 74.5 degree(s)C and 87 degree(s)C in addition to those reported by earlier workers at 71 degree(s)C, 81 degree(s)C and 90 degree(s)C. These findings have been corroborated by the analysis of the thermal runs of the same samples using differential scanning calorimetry.
