Organic Photochemistry can broadly be divided into two, covering either the physical organic chemistry aspects of the subject or the practical application of photochemistry in the synthesis of new molecules. Photochemistry can offer the synthetic organic chemist a high yielding, clean and efficient reaction process, and can give access to structures or stereochemistry that are difficult to prepare in other ways.

This new volume in the Postgraduate Chemistry Series covers synthetic organic photochemistry at postgraduate student and research level. It provides a thorough overview of this important and exciting area of research, demonstrating the underlying principles of synthetic organic photochemistry and, by reference to a range of organic reaction types, it′s effective use in the synthesis of new organic materials.

Written for postgraduate students and those beginning their research careers, the book will also serve as a handy reference for more experienced workers.
