摘要：Cholesteric liquid crystals (CLC) change colour at phase transition temperatures and their sensitivity totemperature depends on the particular characteristic composition. The measurement of ultrasonic velocities helps instudying the nature of intermolecular forces. It also provides significant information about the structure and propertiesof the system. We measured ultrasonic velocity of Cholesteryl Myristate as a function of temperature in the temperaturerange 700C to 900C by changing the concentration of CLC in the solvent. We observed anomalous behaviour in theproperties of CLC near phase transition temperatures for all the concentrations. These physicochemical properties alsovaried with the concentration of CLC in the solvent. This behaviour is due to the physicochemical changes in the LCmolecules. The study of the physicochemical properties has applications in basic science, industries and biochemicaltechnologies.
