Thickness Dependence of Refractivity in Wall-Adjacent Epitropic Liquid Crystal
Section: Solid matter
Abstract: Peculiarities of the behavior of some optical characteristics of orientationally ordered walladjacent layers of nonmesogenic liquids – epitropic liquid crystals (ELC) – are analyzed. A suggested model develops the well-known Maier–Saupe–Neugebauer theory and takes a twocomponent structure of ELC (dynamic equilibrium between monomers and dimers) into account. The experimentally measured thickness and temperature dependences of the refractive index and the value of birefringence are in good agreement with theoretical calculations.
Key words: orientationally ordered wall-adjacent layer; dimer, monomer, refractive index, birefringence.
