Abstract
Recently synthesized antiferroelectric liquid crystal 1H6Bi showsspecial optical properties related to change in handedness of the ferroelectric helix. The broadband dielectric measurements of this compound has been carried out, a number of dielectric relaxation modes corresponding to various temperatures and LC phases have been detected. The characteristic parameters of these modes are presented and compared with the optical data.
