An induced dipole model of the smectic c phase

TLDR
In this article, a model of the smectic C phase is proposed in which the tilt is thought to originate from the forces between dipoles and induced dipoles, where the rotation about the long axis is assumed to be free.
Abstract
A model of the smectic C phase is proposed in which the tilt is thought to originate from the forces between dipoles and induced dipoles. The rotation about the long axis is assumed to be free. Three ordered phases are found corresponding with the smectic C phase, the smectic A phase and the nematic phase. The entropy of packing plays an important role in the mechanism of the smectic C-smectic A phase transition. This transition is not of the usual order-disorder type.
