## 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
Institute, Department of Chemistry, Polytechnic Institute of ## S J nopsis We have studied the helix coil transition for poly-7-ethyl-bglutamate (PELG) in the mixed solvent system: trifluoroacetic acid-trifluoroethanol by high rpsolution nuclear magnetic resonance spectroscopy. At 2 5 O , the tra
