The infrared absorption of poly-L-proline in concentrated aqueous salt solutions was measured in the fundanierital region. Of primary interest were the carbonyl absorption of the peptide linkage and the methylene C-H bending absorption of the pyrrolidine ring. These spectral regions each show an add

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
