Theory of a Dielectric Loss in Long Chain Polar Compounds

A new model is proposed which gives a dielectric absorption for long chain polar compounds. Under the influence of an alternating applied field the equilibrium distribution of the dipoles is disturbed and it is supposed that a steady state is attained by each dipole interacting with its own molecular chain, the chains themselves always maintaining their equilibrium distribution. The frequency dependent dielectric constant is found to be of the form (ω) = const.(1 + i ωτ) -1 where τ is a collision time. The present theory does not preclude the co-existence of any of the other well-known types of dielectric absorption.
