Abstract:   The refractive indices of N- (p-n-heptyloxy benzylidene)–p-n-methyl aniline (7O.1) LC substance was measured with the aid of a modified spectrometer at three different wavelengths. The wavelength-dependent refractive indices were fitted using three and two coefficient Cauchy design. For high birefringence liquid crystals three coefficient Cauchy model is favorable than two coefficient model and vice versa. The results obtained are compared and discussed.
