The dielectric relaxation phenomena of rigid polar liquid molecules chloral and ethyltrichloroacetate ( j) in benzene, n-hexane and n-heptane (i) under 4.2, 9.8 and 24.6 GHz electric fields at 30 AE C are studied to show the possible existence of double relaxation times τ 2 and τ 1 for rotations of the whole and the flexible parts of molecules. The probability of showing double relaxation is more in aliphatic solvents indicating their nonrigidity. The symmetric and asymmetric distribution parameters γ and δ are obtained from χ
