Abstract
Three selected compounds with a rich liquid crystalline polymorphism o f chiral tilted smectic phases were investigated with respect to their pyroelectric behaviour. Measurements for well aligned samples are pre sented with high temperature resolution and are compared to the calori metric behaviour. Data of the temperature dependence of the spontaneou s polarization is derived for all smectic phases under investigation a nd compared to the behaviour obtained for the smectic C phase by the triangular wave method.
