Abstract: 
Mobile-phase Cu(His)2 complexes in water at room temperature in the presence of excess histidine are characterized by ESRmethods. In order to identify the nitrogen donor atom, histidine, for which I4N in the imidazole ring is substituted with I5N, wasused. Spectra in the presence of excess histidine have been analyzed by simulation of second-derivative spectra and by Fourierand reverse Fourier transforms of the spectra. It is concluded that the spectra arise from a superposition of an 80% contributionfrom complexes formed with two histidines in a histamine-like configuration and a 20% contribution from complexes with twohistidines: one glycine-like and one histamine-like. It is suggested that Fourier and reverse Fourier transforms are particularlyeffective methods to analyze the nitrogen superhyperfine patterns in spectra from copper-histidine complexes.
