A significantly updated translation of Lichtabsorption und Photochemie Organischer Molekule, published by VCH in 1989. A graduate textbook that provides a qualitative description of electronic excitation in organic molecules and of the associated spectroscopy, photophysics, and photochemistry. The treatment is non- mathematical and emphasizes the use of simple qualitative models for developing an intuitive feeling for the course of photophysical and photochemical processes in terms of potential energy hypersurfaces. Special attention is paid to recent developments, particularly to the role of conical intersections. Annotation copyright by Book News, Inc., Portland, OR

A unique look at some of the hottest topics in photophysics and photochemistry today The study of molecules in excited states has exploded over the past decade, providing new insights into conformational changes in organic molecules and opening up research opportunities for scientists and professionals in chemistry, physics, biology, medicine, and materials engineering. Using conformational analysis as a unifying concept, this important new work provides readers with a cohesive and cutting-edge overview of this fascinating and challenging field. From conformational changes accompanying photoinduced electron transfer to elementary photophysical and photochemical processes in living systems, the most representative and challenging topics are carefully gleaned from the vast literature, highlighting major conceptual problems along with the relevant experimental techniques. Authoritative, detailed contributions from both experimentalists and theoreticians include coverage of: * Conformational changes in intramolecular excited state electron transfer * Conformational aspects of excited state proton transfer * The novel topic of solute-solvent friction in chemical reactions * Mechanisms and structural aspects of exciplex formations * Conformational aspects of organic photochemistry * Calculations of excited state conformational properties

Photochemical reactions provide a complementary strategy for the synthesis of complex organic molecules as it often involves multiple bond formation in a single step. However, use of organic photoreaction as a common tool in synthesis is limited due to challenges associated with controlling their excited state properties. Altering the molecular framework has the potential to alter their excited state features opening new reactive pathways. This requires in depth understanding of reactivity and excited state dynamics. This dissertation details an effort to engineer new excited state reactions of organic molecules. Fundamentals of organic photochemistry and various strategies that were developed in this field are discussed in the first chapter. It details concepts related to organic photoreactions and asymmetric photochemical transformations, which are known to be quite challenging due to short life time and high energetics of the reactive excited states. The chapter details various methodologies that are developed and successfully implemented for controlling photochemical reactions. Second chapter describes photocycloaddition of an excited alkene to a carbonyl group. Due to the difference in the nature of orbital that initiates the cycloaddition, the reaction was labeled as Transposed Paternò-Büchi reaction. The strategy developed in this chapter is different from normal Paternò-Büchi, where an excited state carbonyl functionality adds to a ground state alkene. In-depth investigations were carried out to decipher the excited state in the reaction pathway with a likely mechanistic rationale. Chapter three details the photocycloaddition of excited alkenes with statistical and nonstabilized imines. This newly uncovered reaction was labeled as Aza Paternò-Büchi reaction. This new reaction was deciphered using photophysical studies. The reactive modes were This new reaction was deciphered using photophysical studies. The reactive modes were Fourth chapter details entropic effects as a tool to control chemoselectvity involving intramolecular [2+2] vs [3+2]-photocycloaddition. The physical properties for entropic control were deciphered due to [2+2] and [3+2] cycloaddition.

Of all major branches of organic chemistry, I think none has undergone such a rapid, even explosive, development during the past twenty-five years as organic photochemistry. Prior to about 1960, photochemistry was still widely regarded as a branch of physical chemistry which might perhaps have oc casional applications in the generation of free radicals. Strangely enough, this attitude to the subject had developed despite such early signs of promise as the photodimerization of anthracene first observed by Fritzsche in 1866, and some strikingly original pioneering work by Ciamician and Silber in the early years of this century. These latter workers first reported such varied photo reactions as the photoisomerization of carvenone to carvone camphor, the photodimerization of stilbene, and the photoisomerization of o-nitrobenzal dehyde to o-nitrosobenzoic acid; yet organic chemists continued for another fifty years or so to rely almost wholly on thermal rather than photochemical methods of activation in organic synthesis-truly a dark age. When my colleagues and I first began in the 1950s to study the synthetic possibilities of photoexcitation in the chemistry of benzene and its derivatives, virtually all the prior reports had indicated that benzene was stable to ultraviolet radiation. Yet I think it fair to say that more different types of photoreactions than thermal reactions of the benzene ring are now known. Comparable growth of knowledge has occurred in other branches of organic photochemistry, and photochemical techniques have in particular made possible or simplified the synthesis of numerous highly strained organic molecules.
