Exceptionally thorough and well written, Principles of Molecular Photochemistry will be useful to every active researcher in the field. Filled with reference material for experts, the book also gives an excellent introduction to photochemical reactivity for students. Developed from Nick Turro's best-selling text for three decades, Modern Molecular Photochemistry, this book develops photochemical and photophysical concepts from a small set of familiar principles and provides clear descriptions in pictorial terms. This text will be of interest to not only practicing photochemists and their students, but also to biological scientists, polymer scientists, material scientists and nanoscientists.
