Kerr Effect of Some New Organic Kerr Solutions

The electro optic Kerr constant of many new organic solutions comprising of the substituted aromatic carbonyl and nitrile compounds as solutes in nitrobenzene, for various molar concentrations of the solutes has been measured. We found several solutions having Kerr constants greater than that of nitrobenzene. The interactions between the components in these solutions have been established to be dipole-dipole in nature for the first time by conducting experiments and measuring the dipolemoments for solutions of various molar concentrations. The variations of the dipole moment with concentration in many solutions have been found to follow the same trend of variations of Kerr constant with molar concentration.
