The observable histidine radical cation generated by collision‐induced dissociation of the [Cu II (2,2′:6′,2′′‐terpyridine)(His)] .2+ complex carries the positive charge on the protonated imidazole ring and the radical formally on the α carbon. This structure has been confirmed by infrared multiple photon dissociation (IRMPD) spectroscopy and density functional calculations.
