The geometry of the title molecule, N-isopropylbicyclo-[2.2.1]heptane-endo-2,3-dicarboximide, C12H17NO2, has been confirmed as the endo conformation. The orientation of the isopropyl (iPr) group relative to the succinimide moiety is a little unsymmetric and the iPr group rotates ca 6 ° around the N - C bond from the perpendicular configuration. This causes the stereoselectivity of the photoreaction in the solid state. The diastereoexcess of the ring expansion products indicates that the carbonyl-O atom predominantly abstracts the nearest γ-hydrogen in the molecule.
