The chain conformation of poly-Lalanine in dichloroacetic acid has been investigated by combining experimental data on optical rotatory dispersions, intrinsic viscosities, and sedimentation equilibria. Comparison of experimentally obtained characteristic ratio with that predicted from theory leads t
High-resolution nuclear magnetic resonance spectra at 100 MHz have been obtained on poly-iV-methyl-L-alanine in the chloroform-trifluoroacetic acid system under various conditions of solvent composition. Different spectra are observed for the CH,-C,, C,-H, and N-CHI protons. On the basis of conforma
## Abstract The conformational transition of polyβLβtyrosine in 0.1__M__ KCl was investigated by ORD and infrared spectroscopy, potentiometric titration, and sedimentation velocity experiments. It is shown that the fully ordered conformer is obtained by slow titration of the random coil with 0.1__N
