Abstract
The rotation of molecules around their long axes is influenced by the in-pl ane order in smectic phases. Assuming a Brownian reorientation process, the effect of polar and quadrupolar order on the dielectric spectrum is invest igated. In the case of quadrupolar order two modes should be visible, while only one mode arises if the order is polar.
