Abstract
We have observed the absorbance vs polarizer rotation angle for the ca rbonyl and phenyl ring stretching peaks in an antiferroelectric liquid crystal, 4-(1-methylheptyloxycarbonyl)phenyl 4'-octyloxybiphenyl-4-ca rboxylate (MHPOBC),and found that the carbonyl group near the chiral c enter rather lies on the tilt plane in antiferroelectric Sm-C-A while it takes a considerably upright position in ferroelectric Sm-C. The spontaneous polarization exists at smectic layer boundaries and its im portance to stabilize Sm-C-A has been discussed.
