The hfcc calculated by averaging values for equivalent nuclei. 5. Simulation of EPR spectra Simulation of the EPR spectra was done with the PEST program (EPR-WinSim.2002 version 0.98 for Windows; available at: using results of B3LYP/EPR-II//B3LYP/6-31G(2d,p) for initial input. The resulting hfcc values were perturbed until the global minimum for the fit was achieved. Spectra used for simulation were generated by reflection of the left half of each spectrum. S 75
