Experimental techniques used in the present work for the measurement of density, acoustical parameters such as ultrasonic velocity, Specific Acoustic Impedance, Adiabatic compressibility, Apparent molar volume, Apparent molar compressibility, Intermolecular Free Length, Rao’s Constant, Molar compressibility or Wada’s constant, Isentropic compressibility, Relative association, Isothermal compressibility, Isothermal expansion co-efficient, Free volume and Internal pressure and Ultrasonic attenuation have been evaluated. Parameters which have been evaluated using theoretical equations. Specifically, experimental techniques used in the present chapter are principle of interferometric measurement.
