Abstract
The general partition function of the preceding paper is applied to the special cases of smectic-$A$ and nematic liquid crystals and isotropic liquids in bulk phases. The relative stabilities of the isotropic, nematic, smectic-$A$, and reentrant-nematic phases are studied as a fucntion of temperature, pressure, tail flexibility, and tail length. The following thermodynamic and molecular ordering properties are studied in these phases and at the phase transitions: smectic-$A$ order parameter, core and tail intermolecular orientational order parameters, tail intramolecular orientational order parameter, density, and entropy. The role of the semiflexible tails in stabilizing the smectic-$A$ and reentrant-nematic phases is explicitly elucidated.
