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
