DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Electron spin polarization generated from the photoredn. of benzophenone (BP) and its derivs.Several reagents with their cas registry numbers 611-94-9 and 90-96-0 are used here. in the presence of 1,4-diazabicyclo[2,2,2]octane (DABCO) was studied in various solvents. The DABCO cation radical obtained showed a CIDEP spectrum with A/E (absorption/emission) polarization by RPM, while other neutral radicals gave an E/A pattern. Using triplet quenchers, it was confirmed that these RPM signals were generated through the triplet reaction process. The present results revealed that the radical ion pair including the BP anion and DABCO+× cation radicals has a pos. J, while the neutral radical pairs generated under the same condition have a neg. J. The sign of J is independent of the polarity of the org. solvents used. .
