2 M c added LiCl and zero added salt conditions at 37°C. P(Kd ) was determined under high salt conditions in D 2 0 , where the interparticle electrostatic c interactions were assumed to be screened by the salt. P(Kd ) was assumed not to change with a decrease in the salt concentration. Neutron scattering measurements are shown in Fig. 7. c P(Kd ) for L D S resembles that for the spherical objects shown in Fig. 3. 5 Â, R2 = 23 Â, P l = - 0 . 34 χ 10~ Â gave a good fit to the experimental curve. The value of R2 was about 2 Â smaller than the hydrodynamic radius, thus indicating a shell - 1 of bound solvent.

74 mL/g, calculate M p and verify that it is a hexamer. 26, where p0 ~ 1. Substitution of these values and fm = kT/Dp into Eq. 78 χ 10 . Given that the subunit molecular weight is 80,000, the degree of polymerization is 478,000/80,000 - 6. 6. Determination of the Equivalent Hydrodynamic Shape of Regular Solids The discussion in this section is limited to the translational motion of regular solids, viz, the sphere, cylinder, and ellipsoids of revolution. , =^(Dl + D2 + D 3 ) , where the subscripts denote the three principal axes of the molecule.

CHAPTER 3 Translational Diffusion—Hydrodynamic Dissipation "So quiet little Martin William Seagull, startled to get caught under his instructor's fire, surprised himself and became a wizard of low speeds. 0. Introduction Martin William Seagull was able to change his motion through the air by simply altering the position of his feathers relative to the air movement in a light breeze. In a similar manner, the shape of a molecule influences the manner in which the molecule moves through the solution.
