The dielectric constant(ε’) and loss(ε ”)of polar liquids solutions of benzene have been determined at different temperature (290C,350C,400C,450C)at fixed microwave frequency (10.15 GHz)were carried out by Gopala Krishna single frequency concentration method which based on Debye equation has been utilized to analyze the dielectric data (ε’ and ε”) to obtain relaxation time (τ) electric dipole moment (μ). It is observed that dielectric constant and loss varies with concentration linearly. The studies report a determination of relaxation time (τ) electric dipole moment (μ) of Nitrobenzene in benzene solution at different temperature.
