Einstein relation for spherical

The mean (apparent) hydrodynamic diameter, d, was calculated from D p using the Stokes-Einstein relation for spherical particles... 

Macroscopic viscosity, in contrast to microscopic viscosity, should not depend on the size of the protein molecules, but only on the volume fraction ij>. This is well known in the limit of low concentration of protein where the Einstein relation for spherical particles ( ) holds... 

In Table 8.4 we have collected values of Cl quadrupole coupling constants and correlation times for a number of protein-chloride complexes. In a few cases, has been obtained experimentally from a comparison of T and T2 or from the frequency dependence of relaxation. In order to make possible a comparison between different proteins we have also calculated from experimental line width data using correlation times estimated by means of the Debye-Stokes-Einstein relation for spherical molecules. We then proceeded similarly as described in Ref. [4Z1],...
