In the past fifteen years organic photochemistry has undergone a greater change and has stimulated more interest than probably any other area of organic chemistry. What has resulted is a population explosion, that is, an ever-increasing number of organic chemists are publishing important and exciting research papers in this area. Professor Bryce-Smith in the introduc tion to a recent volume of the Specialist Periodical Report (Photochemistry, Volume 6), which reviews the photochemical literature in yearly intervals, states that "the flood of photochemical literature is showing some signs of abatement from the high levels of two or three years ago .... " However, Volume 6 of that periodical contains 764 pages of excellent but very concise reviews. We expect the development of the mechanistic aspects of organic photo chemistry to continue at the present pace as new methods are developed to probe in increasing detail and shorter time scales the photochemical dynamics of both old and new photoreactions. Since photochemistry is no longer the sole domain of the specialist, it is relatively safe to predict a dramatic increase in the near future of the synthetic and industrial uses of organic photo chemistry .

Originally published in 1967, this volume contains the proceedings of the first international conference held to discuss the triplet state and the various physical phenomena known to be associated with molecules having orbital electrons with parallel spins, and techniques for their investigation. A number of results and ideas in the field of magnetic resonance and phosphorescence of the triplet state are reported for the first time. The topics covered are spin-orbit coupling, intersystem crossing, magnetic resonance, magnetic interactions, photochemistry, radiationless transitions, triplet excitons, delayed fluorescence, phosphorescence and the triplet state related to biology. This volume brought together knowledge concerning the triplet state and defined the problems in need of solution. The review nature of the plenary papers and the good coverage of the volume as a whole made it a basic reference book on the subject, which is still of relevance today.

Radiationless Transitions is a critical discussion of research studies on the theory and experiments in radiationless transitions. This book is composed of nine chapters, and begins with discussions on the theory and experiment of photophysical processes of single vibronic levels and/or single rovibronic levels. The subsequent chapters deal with the spectroscopic investigations of intramolecular vibrational relaxation; the dynamics of molecular excitation by light; and the photophysical processes of small molecules in condensed phase. The discussions then shift to the high pressure effects on molecular luminescence and the internal conversion involving localized excitations, presenting one qualitative and one quantitative example, as well as the intersystem crossing with localized excitations. A chapter explores the energy transfer processes that occur after a molecule in solution is excited by light, with an emphasis on solid solutions in which the large amplitude molecular motion is largely quenched. This chapter also looks into the liquid solutions in which the molecules can translate and rotate under the influence of fluctuating forces from the liquid. The concluding chapter focuses on ultrafast processes. Researchers in the fields of physics, chemistry, and biology will benefit from this book.

Drawing on the continued wealth of photochemical research, this volume combines reviews on the latest advances in the field with specific topical highlights. Starting with periodical reports of the recent literature on physical and inorganic aspects, light induced reactions in cryogenic matrices, properties of transition-metal compounds, time-resolved spectroscopy, the exploitation of solar energy and the molecules of colour. Coverage continues with highlighted topics, in the second part, from photoresponsive hydrogels, the tunable photoredox properties of organic dyes, light-driven asymmetric organocatalytic processes, dual gold–photoredox catalysis, the preparation and characterization of photosensitizers for triplet–triplet annihilation photon upconversion and the role of photochemistry on traditional synthetic processes. This volume will include for the first time a section entitled ‘SPR Lectures on Photochemistry’, providing examples for academic readers to introduce a photochemistry topic and precious help for students in photochemistry. Providing critical analysis of the topics, this book is essential reading for anyone wanting to keep up to date with the literature on photochemistry and its applications.
