Abstract

As the first part of the study on relaxational behavior of rigid macromolecules in solution, a general method for evaluating diffusion constants of a rigid macromolecule with an arbitrary configuration in a viscous solvent is presented. The evaluation is made by modeling the molecule with a rigid assembly of Stokes spheres. The diffusion constants are expressed by a 6 × 6 matrix which consists of translational, rotational, and cross constants, each being a 3 × 3 submatrix. Procedures of numerical calculation are presented for a given configuration of the molecule, together with some exemplifying results for the rigid rod, rigid sphere, and myosin molecule. The results for the rod and the sphere are compared with analytical results.
