Abstract:
A simple analytical system using light scattering (LS) method has been developed to determine phase transition temperatures of liquid crystals (LC). Intensity changes of the transmission light through a sample were measured as function of temperature. All the LC studied showed appreciable changes in the transmission intensity at the phase transition temperature. The transition temperatures determined by the LS method were identical to those by differential scanning calorimetry (DSC).
