been reported that norbornadiene in a triplet state isomerizes efficiently to a ground state of quadricyclane through a biradicaloidal intermediate on the basis of photochemical investigation of the corresponding cyclic azoalkanes. In the present paper, on the other hand, the authors have found that a naphthalene derivative of quadricyclaneisomerizes inversely to the corresponding norbornadiene derivative
