Characterization of the B6 phase by dielectric measurements

Dielectric measurements on a sample from banana-shaped molecules were carried out between 1 Hz and 10 MHz. The sample exhibits at higher temperatures the B-6 phase and at lower temperatures the B-1 phase. No difference in the dynamical behaviour between these two, phases with respect to the relaxation rimes, dielectric increments and distribution parameters could be detected. Both phases show a negative dipole correlation for the reorientation of the dipoles in the stiff middle part about the long axes.
