Abstract: | Dielectric measurements on a sample from banana-shaped molecules were carried out between 1Hz and 10MHz. The sample exhibits at higher temperatures the B6 phase and at lower temperatures the B1 phase. No difference in the dynamical behaviour between these two phases with respect to the relaxation times, 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. |
