Abstract
From the low frequency order parameter fluctuation spectrum of chiral DOBAMBC at the ferroelectric smectic A to C transition, studied by dielectric relaxation spectroscopy, the frequency and dielectric strength of the Golds tone mode for q = 0 in the ferroelectric phase have been determined. The frequency is approximately temperature independent, decreasing slightly when approaching Tc from below, while the intensity decreases for an order of magnitude and goes to zero at Tc.Keywords
