dc.description.abstractA theory is developed of the anomalous magnetic and electric birefringence in the isotropic phase of nematic liquid crystals taking into account orientational orrelations between neighbouridg molecules. Use is made of a modification of Bethe's method due to Krieger and James, and the properties of the system are derived in terms of a single parameter, viz., the two-partide interaction constant. The expressions for the magnetic and electric birefringence are similar in form to those given by the phenomeno- logical model of de Gennes. Theoretical curves for p-azoxyanisole reproduce the trends in the observed data. A calculation of the nematic-isotropic transition point confirms that this treatment is an improvement over the mean field approximation in describing pre-transition phenomena in the isotropic phase.en
