Dipolar process vibration polarization

A dipolar process is described in terms of three quantities the orientation polarization, the vibrational polarization, and the relaxation time. The first of the three is expressed as A =85-8oc, where is as defined earlier, and is the limiting high-frequency permittivity. The vibrational polarization is expressed as A8vib=eoo- op. where op is the refractive index of the material, usually at the...
