Abstract

The polarized absorption spectra of the naphthalene bicarboxylic acid derivatives dissolved in nematic liquid crystal mixture ZLI 1695 have been studied in the ultraviolet and visible spectral region. On the basis of these spectra the degree of anisotropy and the order parameters S and D have been determined as a function of temperature. The experimental data have been compared with theoretical calculations predicted by the mean field theory.
