In 1957, O'Konski and Haltner investigated electric birefringence in dilute solutions of tobacco mosaic virus (TMV) in alternating fields. The magnitude of the intrinsic Kerr constant, its frequency dependence and the transient behavior show that the orientation is produced by an induced polarization and that the permanent dipole coupling is negligible. They explained their experimental results by assuming that the transient birefringence follows the first-order rate law. It is the aim of this paper to calculate the electric birefringence in dilute solutions of TMV in alternating fields with the aid of the distribution functions. The theory is in agreement with the experimental results in that i) the phase retardation of the birefringence relative to the field is proportional to the frequency, ii) the maximum and minimum values of the steady-state birefringence are unity and zero at zero frequency and both values become asymptotically 1/2 with increasing frequency and iii) the magnitude of birefringence decreases rapidly when, the frequency is increased beyond 30kc/sec.
