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 B10 and a polarization-dependent part ∝P02/q2. For q<105 cm-1, the polarization-dependent term is much larger than B10.
