Refractive indices, order parameter and optical transmittance studies of a nematic liquid crystal mixture

摘要: Measurements of ordinary refractive index, birefringence, density, and order parameter were made on a technologically important nematogen the data obtained for its nematic isotropic phase reported. A modified wedge method was used measurement birefringence (delta n). The nematic-isotropic transition temperature matches very well as is exhibited from value indices densities using different techniques. optical anisotropy density to determine principal polarizability mixture Vuks approach their dependence discussed. macroscopic compared with microscopic parameter. These two values agree well.
