Effect of the Angular Velocity on the Sedimentation Constant of Rodlike Macromolecules, II.

Abstract

The sedimentation constant of rodlike macromolecules decreases with increasing angular velocity of the ultracentrifuge. In the previous paper (Japan. J. appl. Phys. 2 (1963) 1), this fact was explained as due to the orientation of macromolecules by assuming that the ultracentrifugal forces acting on the molecule are parallel. In this paper non-parallel nature of the ultracentrifugal forces is taken into account and the results of the previous paper are corrected.
