Abstract
High‐resolution nuclear magnetic resonance spectra at 100 MHz have been obtained on poly‐N‐methyl‐L‐alanine in the chloroform–trifluoroacetic acid system under various conditions of solvent composition. Different spectra are observed for the CH3–Cα, Cα–H, and N–CH3 protons. On the basis of conformational analysis an interpretation of the NMR results was attempted.Keywords
