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
## Abstract Certain discrepancies in measured heats of helix–coil transitions in polypeptides are examined in terms of the theory of the effect of solvent composition on transition temperatures and heats in such systems. It is found, generally, that disagreement between enthalpy measurements conduc
