confirmed the generation of a paramagnetic species at low temperature. Because the cross-linked compound lacks beta-methylene protons, the EPR lineshape was dramatically altered when compared to that of the tyrosyl radical. However, simulation of the EPR lineshape and measurement of the isotropic g value was consistent with a small coupling to the imidazole nitrogen and with little spin density perturbation
