Paper Abstract

The absorption spectra of some dichroic dyes: derivatives of naphthalenebicarboxylic acid and of naphthoylenobenzimidazole in nematogenic liquid crystalline mixture ZLI 1695 have been studied in details using polarized light. On the basis of these spectra the order parameters S and D have been determined by using the theoretical relation D equals f(S) and proper calculation procedure. Moreover, the absorption transition moment directions with respect to the long axis of the dye have been assigned.
