  • Abstract
    The present study reports dielectric study of newly synthesized unusual H shaped mesogenic dimer. We have performed dielectric study with temperature variation in the frequency range 100 Hz to 40 MHz. The present study is important due to unusual shape of these liquid crystal dimer. The dielectric results suggest that relaxation mode has been observed in MHz region for the sample . For the sample relaxation mode follows Cole-Cole theory. Relaxation frequency and relaxation strength have been evaluated from Cole-Cole plot. In addition to this, activation energy has also been calculated from Arrhenius plot showing higher value than other conventional liquid crystal material.
