Complex formation of poly(glutumic acid) with cupric ions in aqueous solution was investigated by three different methods: optical spectroscopy, optical rotatory dispersion, and electron spin resonance. Formation of a characteristic complex was found to occur in a pH region suitable for the helix‐coil transition. An analysis of the ESH spectrum of the complex is given, and the results of calculation of bonding parameters suggest that the bond between copper and nitrogen atoms had an appreciably covalent character. The change in the secondary structure of the polymer as a result of complex formation is discussed.
