Rotational viscosity of induced smectic C* phase of liquid crystal

Abstract

The rotation viscosity and the molecular tilt angle 0 have been determined in smectic layers of induced ferroelectric liquid crystal system containing some 1R, 4R-2-(4-phenyl-benzylidene)-p-menthane-3-one derivatives as chiral dopants. The correlation between the rotational viscosity and the angle 0 has been studied. The temperature dependence of the smectic tilt angle.
