Abstract
A theoretical relation has been developed from the Landau free energy expansion between SmC-SmA phase transition temperature of chiral smect ic compound and that of its nonchiral analogue. The bilinear and biqua dratic coupling constant and the quadrupolar order parameter have been determined from the extended microscopic model in the chiral smectic- C (Sm-C) phase of four ferroelectric liquid crystal (FLC) materials a nd results have been discussed.
