| Abstract: | In four substances exhibiting reentrant nematic phases the threshold voltage of the Freedericksz transition was measured as function of the frequency in the nematic and reentrant nematic phases. The isotropy frequency and the relaxation frequency were calculated using the experimental data. We found that extrapolated to the same temperature the relaxation frequency of the reentrant nematic phase is larger than that of the nematic phase. |
