Modern Molecular Photochemistry of Organic Molecules is a comprehensive revision of Turro’s classic text, Modern Molecular Photochemistry, which has been the standard of the field for three decades. For a crystal-clear introduction to organic photochemistry in pictorial terms, this book comprises all of the same introductory chapters that make up Principles of Molecular Photochemistry, but then goes on to provide additional chapters that cover the methods for determining the mechanisms of organic photoreactions, and describe comprehensively the photochemistry of the basic functional groups of organic chemistry. The text also includes special topic chapters on supramolecule organic photochemistry, the first of its kind, and the role of triplet and singlet molecular oxygen in organic photochemistry. 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 who use photochemistry and photophysics in their research and teaching.
