L-band EPR of 63Cu(II)-imidazole (Cu-Im). The sets of traces A and B are the experimental L-band EPR spectra (thick lines) of Cu-Im overlaid on simulations assuming three (A) and four (B) coordinated nitrogen atoms, respectively. Trace C is the first integral of the modulus of the residual, ∫ |[(∂χ″/∂B)exp − (∂χ″/∂B)sim]| dB, where the residual (∂χ″/∂B)exp − (∂χ″/∂B)sim was obtained by subtraction of the ∂χ″/∂B three-nitrogen simulation from the ∂χ″/∂B experimental spectrum. Trace D is the corresponding ∫|[(∂χ″/∂B)exp − (∂χ″/∂B)sim]| dB for the four-nitrogen simulation.
