Abstract

Exposure of aqueous solutions of alkali-metal bromides or iodides to ⁶⁰Co γ-rays at 77 K gave hydroxyl radicals, Br₂ ^– or I₂ ^–, and species identified as BrOH^– or IOH^–. The resulting magnetic parameters are compared with those for V_K centres in alkali halide crystals, and with CIOH^– in strontium chloride hexahydrate. Argentic and mercuric iodide complexes in frozen aqueous solution gave only I₂ ^– under these conditions.
