X-ray diffraction patterns from two different nematic samples viz (i) 1-hexyl-4-(4-isothiocyanatophenyl) bicyclo [2,2,2] octane and (ii) 4′-(pentyloxy)-4-biphenyl carbonitrile, were recorded using Laue type of arrangement, consisting of flat 2D- image plate detector. Using these recorded data and employing three different models orientational order parameter [1 Falgueirettes , J. ( 1959 ). Bull. Soc. Frac. Miner. Cryst ., 82 , 151 . [Google Scholar]] ⟨P2⟩ and the higher order parameter ⟨P4⟩, have been computed and analyzed. The order parameters estimated from X-ray method is also compared with that obtained from optical method.
