synthesized and irradiated under sensitized conditions. The compounds 12 - 15 yielded di-π-methanerearrangement products. 16 was not reactive. The quantum yields for product formation were measured. They increase with ring strain of the bicyclic systems. A kinetic isotope effect on the regiospecifity of the rearrangement was observed in all cases. In addition, an isotope effect on the quantum yields of
