Photogeneration of singlet oxygen by psoralens
Bulletin of Experimental Biology and Medicine, 1983Photosensitized luminescence of singlet (1 delta g) molecular oxygen with the maximum at 1272 nm has been found in solutions of psoralen, angelicin and 8-methoxypsoralen in CCl4. The luminescence excitation spectra, quantum yields of generation (gamma g) and rate constants of quenching (Kq) of 1 delta g by psoralens have been measured.

Cytogenetic effects of singlet oxygen
Journal of Photochemistry and Photobiology B: Biology, 1992Singlet oxygen was generated in the gas phase at atmospheric pressure by the method of heterogeneous photosensitization. In vitro exposure of human lung WI-38 fibroblasts to gas-phase singlet oxygen resulted in sister chromatid exchange.

Photosensitized Generation of Singlet Oxygen
Photochemistry and Photobiology, 2006This work gives an overview of what is currently known about the mechanisms of the photosensitized production of singlet oxygen. Quenching of pi pi* excited triplet states by O2 proceeds via internal conversion of excited encounter complexes and exciplexes of sensitizer and O2.
