Newman et al. (1974) have recently studied the concentration-dependence of the diffusion coefficient and the sedimentation coefficient in a highly monodisperse solution of the single-stranded circular DNA from the fd Bacteriophage. Their results are shown in Fig. 13.5.3. From these data it is possible to determine the coefficients in the expression... 

Fig. 2. (Comparison of the theoretical diffusion curves and actual sedimentation diagrams for E. colt bacteriophage T6 at pH 4.9. The solid line curves represent the mean ordinate of the sehlieren curve (corrected for camera magnification) and the circles denote the theoretical boundary diagram calculated from the diffusion constant. The position of the meniscus is given by the vertical arrow. Curves are given for 6280, 7200, and 10,080 seconds after the beginning of acceleration to 3150 r.p.m. (255).

In several studies the detailed nature of motion has been deduced from powder spectra (8-10). For [2,3,5,6- H4]tyrosine in a bacteriophage coat protein (8), a discrimination between fast continuous diffusion and rapid discrete diffusion was made. Fast continuous diffusion about the bond (Figure 5) would...
