摘要：

Quasielastic light-scattering measurements are reported for a chiral smectic-C material as a function of enantiomer concentration and applied electric field, The elastic constant B1 and associated viscosity have been determined. More importantly, it was found that B1 is composed of a bare part B-1(0) and a polarization-dependent part is-proportional-to P-0(2)/q2. For wave vector q < 10(5) cm-1, the polarization-dependent term is much larger than B-1(0).
