Low-temperature irradiations of 1-phenylcyclohexene (PC6) yield two singlet state 2 + 2 photodimers and two 4 + 2 cycloadducts. The 4 + 2 adducts are not observed in low intensity lamp irradiations at room temperature but are produced in significant quantities when PC6 solutions are subjected to higher intensity laser irradiation. The results indicate a reaction mechanism involving two trans-PC6 molecules
