Reviewing photo-induced processes that have relevance to a wide number of academic and commercial disciplines, this volume reflects the current interests in chemistry, physics, biology and technology. Section one covers organic and computational aspects of photochemistry while Section two highlights topics like photomagnetism in organic dyes, in silico photochemistry and delayed fluorescence in photosynthetic systems. The final section covers the SPR lectures on photochemistry on photoredox catalysis in synthesis, perfluoroalkylation of aliphatic substrates via photoinduced radical processes and photocycloadditions of aromatic compounds with alkenes. The volume continues to provide essential reading for postgraduates, academics and industrialists working in the field of photochemistry, enabling them to keep on top of the literature.
