Exposure of various bromo- and iodo-imidazoles as dilute solutions in methanol or methyltetrahydrofuran at 77 K to 60Co γ-rays resulted in electron addition to yield major species which were not the expected π* radical anions but σ* radical anions, the SOMO being primarily the C-hal σ* orbital with little delocalisation.
