Abstract

High-resolution heat-capacity measurements have been carried out on the chiral and racemic versions of 2-methylbutyl-4-n-pentyloxy-biphenyl-4- carboxylate (2M45OBC). Both smectic-A smectic-C and smectic-Achiral-smectic-C transitions are found to be mean-field-like with a large sixth-order term in the Landau free-energy expansion. Our results also shed light on similarities and differences between the chiral and racemic compounds.
