“…These optical properties provide important information about molecular ordering, molecular dynamics and the nature of molecular interactions. There are a number of techniques available for studying the temperature dependence of the optical properties of liquid crystals, including trinocular polarising microscope techniques [4], the Z-Scan technique [5], techniques involving study of the continuous wavelength of the ultraviolet and infrared spectral regions [6], the Abbe refractometer [7], the wedge technique [8,9], the hollow prism method [10] and the FabryPérot interferometer [11]. These methods each require different experimental setups in order to investigate the optical properties of liquid crystals.…”
