Published theoretical equations for the sedimentation coefficient and intrinsic viscosity of a semiflexible chain are compared, neglecting the excluded volume effect. The theories are extended to the case of a small excluded volume, by applying the perturbation theory, established for flexible chains, to a semiflexible chain. Using the derived equation, the experimental results for the sedimentation coefficient and intrinsic viscosity of DNA and cellulose trinitrate are analyzed.
