This calculation of the dielectric constant is performed for the pure optically active compound (T-c = 73.4 degrees C) and the temperature range is determined for a first-order smectic A-smectic C* transition from the mean field model. Our predicted values describe adequately the observed behaviour of the dielectric constant close to the smectic A-smectic C* transition and also the temperature range in the smectic A phase of A7.eninfo:eu-repo/semantics/closedAccessDielectric ConstantAc* TransitionA7Conference Object427Q4Q4137142WOS:000305244900017
