The measurements of the polarized absorption and fluorescence components spectra for the guest-host mixtures have been used to study the long orientational order in the uniaxial phases of the liquid crystal. The temperature dependence of the order parameters, ⟨P_{2}⟩ and ⟨P_{4}⟩, has been investigated and the molecular distribution function has been determined. On the basis of the ⟨P_{2}⟩ and ⟨P_{4}⟩, values some conclusions about the molecular orientation in the smectic A and nematic phases of the liquid crystalline samples have been drawn. It has been also found that the fluorescence spectroscopy is a sensitive method for determination of the phase transition temperatures of the liquid crystal doped with the fluorescent dye.
