The dielectric constants and losses have been determined over a wide microwave frequency range for cyclohexane and p-xylene solutions of cholesteryl methyl ether at 25’. The considerable difference in the relaxation times of the molecule and the mobile group produced some separation of the two absorption processes; this enabled a reasonable estimate of the weight factor (C,) governing that process and provided a lower limit for Cz for aromatic methoxy compounds of 0.4. In the literature considerable divergence exists for the CZ values for anisole which ranges between 0.2 and 0.8. The results establish that the Cz value of
