HEIGHT OF DSC PHASE TRANSITION PEAKS - II. SOME APPLICATIONS TO LIQUID CRYSTALS.

Liquid crystal yields liquid crystal and liquid crystal yields isotropic liquid transitions of several materials are studied using a number N, where N is defined as the ratio h prime /h, h and h prime being the heights of the transition peaks at heating rates T//p and 2T//p respectively. N is found close to two, which shows that a heat capacity increase occurs near the transition temperature, in agremeent with the current theories describing these transitions.
