Pretransitional optical activity of short-pitched chiral nematic liquid crystals.
We have developed, using the de Gennes theory of short-range orientational order in the isotropic phase, a closed-form expression for the temperature dependence of the pretransitional optical activity of chiral nematics. Detailed calculations are included and the results are expressed in a form that can be easily tested experimentally. The theoretical predictions are supported by experimental data.
