The products resulting from the photolysis of perylene (Ar) in cyclohexane (Cy) using pulsed irradiation at 248 nm from an excimer laser are compared with those obtained using a low pressure mercury lamp at 185 nm. In the laser experiment, the data i

Evidence is presented that the excited singlet and triplet states of aromatic hydrocarbons are oxidised by methyl viologen (MV 2+ ). Rate constants for electron transfer from triplet naphthalene, anthracene, phenanthrene and fluoranthene are close to

Summary Two photochemical reactions are considered, illustrating quantitatively the differences in rate constants for chemical and physical deactivating processes from excited singlet and triplet states, in each case, for the identical photochemical

Examination of the fluorescence spectra of N,N-diethyl-4-phenyl-butylamine (2), and 1-dimethylamino-4-phenylbicyclo-[2,2,2] octane (3), shows that (2) forms an intramolecular exciplex whereas (3) exhibits intramolecular energy transfer from the benze

— The production of singlet oxygen by thiazine dye photosensitization, as measured by the rate of photooxidation of tryptophan, was found to be very sensitive to changes of pH in the range 5–9. For methylene blue in aerated solutions, the product
