• Dielectric measurements have been recorded in the frequency range 0.75-3.0MHz in nematic and isotropic phases of EBBA. Measurements in the nematicphase indicate a Debye-type dispersion. Two activation energies were obtained,one above 47'C (l5.36kcal./mole) and the other below 47'C (9.15 kcal./mole).Dielectric relaxation strength Je(=sg -e,.) also exhibits a peak at 47'C. Theseresults may be explained by assuming the hindered rotation below 47'C anda relatively free rotation above 47'C of the molecules about a transverse axisunder the nematic potential.
