ESR studies of room-temperature gamma irradiated single crystals of imidazole and of its derivatives deuterated in several different positions have permitted us to identify the main radical produced by such one hydrogen atom on a carbon of the ring. Moreover, we show that the hydrogen atom which is added to form the radical comes from hydrogens involved in the hydrogen bond chains. The subsequent ENDOR study enables us to deduce othe spin density distribution in the radical from the determination of all the proton hyperifine tensors. (auth)
