During the photolysis of the endoperoxide of 9,10-diphenylanthracene, two different reactions are observed, depending on the irradiation wavelength: (i) Excitation of the S1 band causes a homolytic cleavage of the peroxide bridge with a quantum yield Q2 = 0.08. (ii) Irradiation of the S2 band leads to an adiabatic photocleavage of the endoperoxide into 9,10-diphenylanthracene and singlet molecular oxygen with a quantum yield Q1 = 0.28. Both reaction pathways confirm the theory of Kearns and Khan concerning the photolysis of endoperoxides
