The purpose of this work was to improve our understanding of quasielastic light scattering from long rigid rods (QL >> 1). For these scatterers, only small angular displacements are required to produce dephasing of the scattering light. This plus the fact that only rods lying perpendicular to Q contribute to the scattered light allow one to simplify the intermediate scattering function to an analytic form. This form is shown to be nonexponential, exhibiting (t)−½ behavior at long delay times. This new scattering function can then be fit to experimental functions using standard methods.
