The dielectric and ultrasonic relaxation study of p-azoxy anisole in benzene and carbon tetrachloride solution at room temperature

The dielectric, conductivity and ultrasonic measurements for p-azoxy anisole are done in its solution in benzene and carbon tetrachloride at room temperature. The dipole moment and relaxation time are computed using a new alternative method as suggested by Johri(1984) and compared with Gopala Krishna microwave method, Higasi and Guggenheim statical methods. Adiabatic compressibility, Rao number, Vanderwaals constant, free volume and specific acoustic impedance are obtained using ultrasonic velocity. Both the solutions show 99 percent solid like behaviour. The measured and evaluated dielectric and ultrasonic parameters provide information about the structure of p-azoxy anisole liquid crystal and about the solute-solvent interaction.
