Static dielectric constants of aqueous solution of methanol were measured at various temperatures. The static dielectric measurements have been achieved by using a sensor which is based on frequency domain reflectomery technique. The excess dielectric properties, Kirkwood correlation factor and Bruggman factor of the binary mixtures have also been calculated and reported. The behavior of excess dielectric permittivity shows positive - negative variations at the studied temperatures suggest the presence of intermolecular interactions in the mixture. The Kirkwood angular correlation factor confirms the parallel and antiparallel orientation of the dipoles in the mixture.
