Niizum, H. Kawata, J. Wan] The photoreaction of the solution system of naphthalene and 2,6-di-tert-butyl-p-cresol was investigated by a combination of optical spectroscopy, ESR and time-resolved CIDEP techniques. ESR signal of 2,6-di-tert-butyl-4-methylphenoxy radical was detected during 308 nm irradiation. Three different types of polarization mechanisms contribute to the CIDEP of the phenoxy radicals. In the initial stage RPM with singlet precursor predominates, whereas RPM with F-pairtnplet precursor persists at later stage. The contribution from TM is superimposed during all the time regions but to a small extent. Both the CIDEP intensity at the initial stage as well as the depletion rate of naphthalene during photolysis were found to be proportional to the square of the light intensity, which indicates that most phenoxy radicals were produced via a biphotonic process.
