Abstract
Flash-photolytic investigations show conclusively that photocoloration in the dianthrones, to form the B isomer, takes place via the triplet state of the starting isomer A. Supporting evidence is provided by triplet sensitization experiments, in which B is formed exclusively, under conditions where isomer C is the sole product of direct excitation of A.
