• Dielectric relaxation times and distribution parameters of three esters in benzene solutions have been evaluated using three methods, <I>viz.</I>, Cole-Cole arc plot method, Higasi's single frequency method and the Gopal Krishna method. Three microwave frequencies have been used to determine <I>a</I>′ and <I>a</I>″ apart from the static and optical frequencies for <I>a</I><SUB>0</SUB> <I>a</I><SUB>∞</SUB>. The distribution parameters obtained from Cole-Cole arc plot and Higasi's method are in good agreement showing that the sploes <I>a</I>′ and <I>a</I>″ have been determined accurately. In these esters the values of the distribution parameter are high. Since the dipole-dipole interactions are negligible in dilute solutions, the higher values of the distribution parameter suggests the existence of multiple relaxation processes.
