11. Experimental X-band EPR spectra were recorded on a Bruker ER220 spectrometer. The spectra were simulated by iteration of the anisotropic g values, (super)hyperfine coupling constants, and line widths. We thank Dr. F. Neese (MPI Strahlenchemie, Mülheim a/d Ruhr, Germany) for a copy of his EPR simulation program.
