Anatomy of the L-band EPR spectrum of Cu(II)-PrPf2 component 2. Trace A is the calculated ∂χ″/dB spectrum of component 2. Trace B is the corresponding absorption spectrum, calculated without including the superhyperfine component due to coordinated nitrogen atoms. Traces C–F are the EPR absorption envelopes for the individual nuclear spin manifolds mI = 3/2, 1/2, − 1/2, and −3/2, respectively. Region G is a region of the spectrum that, in the ∂χ″dB and higher derivative displays, is due solely to the parallel feature of the mI = 1/2 manifold. Region H of the spectrum is due to the overlapping perpendicular features from each of the manifolds. Region I is almost entirely due to the intense extra absorption line of the mI = −1/2 manifold and, therefore, is sensitive to both parallel and perpendicular features.
