Cholesteryl nonanoate takes the left-handed cholesteric liquid crystalline state, cholesteryl chloride takes the right-handed cholesteric liquid crystalline state, and their mixture takes a compensated nematic liquid crystalline state in a limited range of composition (60-70 mol% of cholesteryl chloride). The dielectric properties of this mixture were examined and the die1ectric dispersion is due to Cole-Cole dispersion at a high frequency and to m's law at the low frequency on the mixture. Absolute theory of rate process was applied to the relaxation frequency estimated from the Cole-Cole dispersion, and activation free energy, enthalpy, and entropy of the dipole rotation were calculated.
