Excited States and Photochemistry of Organic Molecules Martin Klessinger Josef Michl This book provides a non-mathematical introduction to electronic excitation in organic molecules, and offers an integrated view of the principles of electronic spectroscopy, photophysics, and photochemistry. This is the first book to incorporate recent advances in understanding the role of conical intersections in photochemical and photophysical processes. Throughout the book, the concepts of potential energy surfaces, bonding theory, and molecular electronic structure in the understanding of photochemistry are emphasized. Simple and intuitive qualitative models for the nature of electronic states are used to explain how electronic structure can be probed by spectroscopy with ordinary and polarized light, including natural and magnetic circular dichroism. Every chapter includes worked examples that illustrate practical applications of theory, as well as extensive references to the original literature. Excited States and Photochemistry of Organic Molecules is suitable for use as a text for graduate and advanced undergraduate students in physical organic chemistry and photochemistry.
