Angular Dependence of Selective Reflection from the Chiral Smectic C Phase

Abstract

Abstract Transmission spectra were measured with obliquely incident light for a chiral smectic C phase of (+)-4-n-hexyloxyphenyl 4−(2″-methyl-butyl)biphenyl 4′-carboxylate. Extra reflection bands were observed at about twice the wavelengths of the “normal” Bragg reflection bands, which had been previously predicted by the computor calculation by Berreman.
