The photochemistry of five- and six-membered cyclanones has played an important role in the development of mechanistic organic chemistry and in our knowledge of biradicals. The dominant primaryphotochemicalprocess of these alkanones is homolytic ..cap alpha..-cleavage (type I process) of a T/sub 1/ (n,..pi..*) state which produces a triplet biradical. The latter is stabilized after intersystem crossing
