Early experiments by a number of workers demonstrated that dye excited states could function as electron donors (69,92-94). Lindquist (69) showed that the triplet state of fluorescein was quenched by oxygen in basic media with the formation of superoxide anion, by ferric ion in acid media to form ferrous ion, and by peroxydisulfate ions in alkaline solutions. The photo-... [Pg.475]
