Optical anisotropies 7 2 of N-t-butylacetamide (tBA), N-methylacetamide (MA), and N,N-dimethylacetamide (DMA) have been determined from the Rayleigh ratios for depolarized scattering by dilute solutions of the amides in p-dioxane. Traceless optical polarizability tensors & for the amides are derived

## Synopsis The sedimentation coefficient sN of the DNA topoisomer with the linking number N is evaluated as a function of N and chain length on the basis of a (circular) twisted wormlike chain, i.e., a special case of the helical wormlike chain. Evaluation is carried out by an application of the
The mean-square radius (S'), of gyration of the DNA topoisomer with the linking number N is evaluated as a function of N and chain length L on the basis of a (circular) twisted wormlike chain, i.e., a special case of the helical wormlike chain. Evaluation of (S2), and also of the moment ( W r 2 ) of
## Abstract The dynamics of the wormlike chain model for a polymer in solution is investigated in the case of free torsional and no longitudinal variations. A Langevin equation is derived and solved for circularly closed chains, neglecting hydrodynamic interactions. The local diffusion behavior of
