POLARIZED RAMAN SCATTERING STUDY FOR FRUSTOELECTRIC LIQUID CRYSTALS

Abstract

Orientational ordering for two types of "V-shaped" switching liquid crystals was investigated by polarized Raman scattering measurements. The measurements were performed not only under the static electric field but also in the dynamic switching process and the second and the fourth order of apparent orientational order parameters were obtained. It was suggested that one liquid crystal oriented collectively at the tip of the V-shaped switching, while the another liquid crystal orientated rather randomly. Two different types of mechanism could exhibit the same phenomenon of the V-shaped switching.
