In this work scattering dichroism is used to determine the dynamics of the defect structure in a liquid crystalline solution of a racemic mixture formed of equal portions of the L- and D- entantiomers of polybenzyl-l-glutamate at 20% in m-cresol. Since the scattering by an object will be sensitive to the ratio of its size to the wavelength of light, a variable wavelength polarimeter has been devised to determine the influence of shear on the size distribution of the defect structure. The principal results of this paper are the observations that the length scale of the defect structure decreases with application of hydrodynamic forces.
