The helix-coil transition temperature Tc of poly(Y-benzy1 bglutamate) in binary solvent mixtures of dichloroacetic acid and l,bdichlorobutane, 1-chlorooctane, or 1chlorododecane have been measured. A treatment is presented with which the transition enthalpy can be calculated from the observed depend
## Abstract The thermal helix–coil transition of four samples of poly(γ‐benzyl‐L‐glutamate) in the dioxane–dichloroacetic acid (DCA) mixture was studied by optical rotatory dispersion method. The transition occurred at very high DCA content (97.5% by weight) in this system. The transition parameter
Simple approximate expressions have been derived from the theory of Zimm and Bragg for use in the analysis of experimental data on the helix-coil transition in polypeptide. On the basis of the resulting expressions practical procedures are proposed t o determine two basic parameters characterizing a
