Calorimetric study of liquid crystals showing Iso-X-Sm-C^*-Iso phase sequence

Abstract

The heat capacity measurement has been carried out on a liquid crystal which shows the isotropic-chiral-smectic-C-isotropic-X phase sequence. The heat anomaly due to the chiral-smectic-C-isotropic phase transition showed a peculiar thermal hysteresis. A very broad peak in the heat capacity was observed in the isotropic phase.
