The helix-coil transition has been studied by high-resolution NMR for three watersoluble polypeptides. Such systems are better models for protein behavior than those in TFA-CDC13 solvent. An upfield shift of ~7 cps is observed for the a-CH peak of poly(bg1utamic acid) and poly-clysine as the helix c
