The dielectric relaxation time (τ) of binary mixtures of different molar concentrations of pyridine (C 5 H 5 N) and N, N-dimethylacetamide (DMA) in benzene solution has been calculated by using standard microwave techniques and Gopala Krishna's [Trans Farad Soc, 33 (1957) 767.] single frequency (9.875 GHz) concentration variational method at different temperatures (25, 30, 35 and 40°C). It is found that the dielectric relaxation time (τ) varies non-linearly with the increasing molar
