Rotatory Motion of Dipolar Molecules Constrained by a Steady Electric Field

Abstract

In this paper a calculation has been carried out on the rotatory diffusion of dipolar rodlike molecules in the presence of an electric field. The time correlation method is used for calculations of dynamic susceptibilities. This calculation has been shown to be in good agreement with the dynamic dielectric studies of Block and Hayes. In addition, the decay of electric birefringence(Kerr effect) in the presence of an electric field has been shown to be extremely sensitive to the relative magnitudes of the steady state field and the initially applied sensing field.
