Abstract
The ππ* triplet excited states of 3-phenyl-2-cyclohexenone (1) and 3-phenyl-2-cyclopentenone (2) have been observed by time-resolved infrared (TRIR) spectroscopy. The reaction of various alkenes with the triplet excited state of 2 has also been studied by TRIR spectroscopy, and the partitioning between fragmentation and ring closure of the biradical intermediates involved has been estimated. Within a series of structurally related biradicals, more stable ones undergo ring closure more efficiently.
