Measurements of dielectric constant and loss have been made at 1 Mc and 9.44 GHz for dibutyl ether and benzophenone in various solvents, <I>e.g.</I>, <I>n</I>-heptane, benzene, cyclohexane, carbon tetrachloride, decalin and Nujol. Whereas, diphenyl ether has only been studied in benzene and cyclohexane. The values of relaxation time and distribution parameter have been determined by using Cole-Cole's equation in terms of the so-called slopes, <I>a</I><SUB>0</SUB>, <I>a</I>′, <I>a</I>″ and <I>a</I><SUB>∞</SUB>. The relaxation time values show a regular increase with the increase in viscosity of the medium both for dibutyl ether and benzophenone. The observations seem to suggest that dibutyl ether relaxes both by molecular and intramolecular mechanisms. The dipole moments in various solvents have also been calculated.
