Featuring contributions from leading experts, Organic Photochemistry and Photophysics addresses the organic photochemistry and photophysical behavior in aromatic molecules, thiocarbonyls, selected porphyrins, and metalloporphyrins. Topics include excited-state proton-transfer reactions of aromatic compounds, the effects of atom transfer reactions to photoamination as a convenient, powerful, and environmentally friendly synthetic process, and how dye structure affects the sequence-dependence of DNA binding. This is a unique, comprehensive reference that discusses topics useful for researchers as well as newcomers to photochemistry, photobiology, photomedicine, and photophysics.
