High-resolution heat-capacity measurement has been carried out on S-4-O-(2-methyl)butyl-resorcylidene-4 prime -octylaniline near its smectic-A-chiral smectic-C transition. Their heat-capacity results combined with the existing tilt-angle data enable the authors to calculate the three leading coefficients in the Landau free energy expression for the smectic-A-chiral smectic-C transition.
