Abstract
We present a novel experimental approach for determining the dynamics of free-standing ferroelectric liquid crystalline films in the frequency range from 1 Hz to 10 3 Hz. By measuring the dynamic infrared dichroism of specific absorption bands in a free-standing FLC-film exposed to rotating external electric fields within a miniaturized electrode arrangement the collective dynamics and the innermolecular response of the FLC system can be analysed. In the SmC * phase a dynamic process is found which corresponds to a resonant switching behaviour which can be described by the model of kink switching. The main contribution to the dynamics of the SmC * phase is caused by the molecular moieties in the mesogenic core.
