The study of a random polar SmC^* like phase asa elucidated by polarized Raman scattering

Abstract

Panarin et al. reported that the phase so far identified as SmA in one component compound of the Inui mixare must be a random polar SmC-like phase, SmC_R. We have studied the same material by using polarized Raman scattering to decide whether it is a SmC_R phase or an ordinary SmA phase. By comparining the experimentally obtained apparent orientationl, order parameters, <P_1> and <P_4>, with the simulated ones, we have concluded that their identification is probably wrong. It must be the ordinary SmA phase but not the random polar SmC-like phase.
