Nmr studies of poly‐γ‐benzyl‐L‐glutamate in trifluoroacetic/deuterochloroform solutions: Temperature dependence

The helix–random‐coil transition process for poly‐γ‐benzyl‐L‐glutamate (PBG) in solvent mixtures trifluoroacetic acid/deuterochloroform (TFA/CDCl3) at different temperatures has been studied by nmr. The chemical shift behavior of the α‐CH resonances of the peptide chain and of the TFA carboxylic protons is reported.
