Optical constants of anisotropic and absorptive liquids

Optical constants, /spl radic//spl epsiv/=n-jk, of the anisotropic and absorptive liquids, i.e., liquid crystal and magnetic fluid, were evaluated by reflectometry in the visible and infrared spectral regions. Semicylindrical prisms were prepared with high-index glass or CsI (cesium iodide) crystal to measure the angular dependence of the attenuated total reflection (ATR) on the sample liquid.
