Translational order parameter in the smectic-B phase of 4-hexyl-4′-[2-(4-isothiocyanatophenyl)ethyl]-1,1′-biphenyl
4-Hexyl-4′-[2-(4-isothiocyanatophenyl)ethyl]-1-1′-biphenyl, a liquid crystalline material shows smectic-B (SmB) and nematic phases, respectively, between 60.3–98.5°C and 98.5–130.8°C. X-ray diffraction patterns were recorded at different temperatures
in the SmB phase and were used to compute translational order parameters. For this purpose, we have employed a theoretical model recently reported by Kapernaum and Giesselmann. The results obtained are discussed in terms of the basic understanding of the SmB phase.
