Abstract

AbstractThe molecular motion during the V‐shaped switching in a homogeneously aligned smectic C*‐like liquid crystal (LC) cell has been investigated by measuring second‐harmonic generation (SHG) interferometry. It was shown that observed SHG behaviors were successfully explained using the collective model and that azimuthal rotation of LC molecules is limited within half a cone and that LC molecules undergo counter azimuthal rotations between the top and bottom halves of the LC chevron layer structure. Possible molecular orientation within a layer was also discussed using the 4 × 4 matrix method.
