## Abstract There have been many reports that the nuclear magnetic resonance (nmr) spectra of a large number of polypeptides exhibit peak doubling of the Ξ±βcarbon and the Ξ±βcarbon proton in the helixβcoil transition region. One apparent exception to this generalization has been polypeptides with io
High-resolution nuclear magnetic resonance spectra at 100 MHz and 220 MHz have been obtained on two samples of poly-Galanine of Mering molecular weights (2500 and 42 500) in the chloroform-trifluoroacetic acid system under various conditions of solvent composition, temperature, and polypeptide conce
