Abstract
Temperature-dependent dielectric spectroscopy of (S)-4′-octyloxybiphenyl-4-carboxylic acid 3-chloro-4-(1-methylheptyloxycarbonyl)phenyl ester (chlorinated MHPOBC analogue) has been carried out in the frequency range from 1 Hz to 10 MHz for sample thicknesses 5, 10 and 20 µm during heating and cooling runs. This compound shows a rich and complex dielectric response, with several active modes in each subphase. Goldstone-mode relaxation has been observed for
