Recently liquid crystal doped with polymer is used to enhance physical and photo physical properties of these materials. The primary subject in the doped liquid crystal is the qualitative determination of the order parameter. Infrared spectroscopy has become the most informative tool in the study of conformation and orientational order of liquid crystalline materials. In the present paper, we used polarized Fourier transform infrared (FT-IR) spectroscopy to analyze the orientational ordering of the liquid crystal doped with polymer. We obtained information about the head orientational order of liquid crystal in these systems by observing the band corresponding to the vibrations of the relevant functional groups.
