Abstract
The principal components of the dielectric tensor in the isotropic, sm ectic A and smectic C* phases have been measured, with emphasis on th e smectic C phase, for a single ferroelectric liquid crystalline comp ound. The dispersion behaviour of the dielectric biaxiality in the chi ral smectic C phase has been determined and it has been established t hat the dielectric biaxiality exhibits a sign reversal for the compoun d studied.
