: A dielectric static permittivity and relaxation study of binary mixtures of organic compounds has been carried out at different concentrations at room temperatures in polar solvents using Time Domain Reflectometry (TDR) technique. By A non-linear Least Squares fit method has been used to obtain the dielectric parameters (the static dielectric constant (ε0) and relaxation time ()). using these parameters, excess permittivity and excess inverse relaxation time were determined and discussed to yield information on the molecular structure and dynamics of the mixture. Relaxation time () indicates the size of newly formed structures decreases with increase in size of organic compounds added to polar solvent (DMSO as well as DMF).
