Chemical and Biological Generation of Excited States discusses major aspects of chemical and biological generation of electronic excitation. This book is organized into 11 chapters that focus on both chemi- and bioenergized processes. This book first discusses some of the fundamental aspects of the description of excited state behavior in condensed media. It then examines the field of gas-phase dioxetane chemiluminescence both by itself and in relation to solution-phase studies. The presented analysis is based on statistical mechanics and supported by a very simple limiting case calculation. Chapter 4 describes the state-of-the-art of how excitation yields are determined experimentally in chemienergized processes. This is followed by a discussion on activation parameters and stability trends, focusing on solution-phase data. Chapters 6 and 7 examine solution-phase chemiluminescence resulting from high-energy electron-transfer reaction, often involving aromatic radical ions, and the mechanism of excitation step. The next chapters cover the generation of electronic excited states in bioluminescence and the evaluation of luminescent oxidation mechanisms using oxygen tracers. The chapters also explain the formation of electronically excited products in dark biological processes and the mechanism of chemiexcitation as it relates to redox metabolism. Specific examples of biological oxygenation reactions yielding luminescence are also presented. Furthermore, this book discusses the concept and applicability of chemiluminigenic probing for the quantification and differentiation of oxygenation activities in mammalian phagocytes. The concluding chapter is devoted to the possible formation of singlet oxygen in various systems and processes that mimic singlet oxygen reactions. The book intends to attract young scientists as well as established research workers to broaden the horizons of this rapidly growing and potentially very important field.

This book gives an extensive description of the state-of-the-art in research on excited-state hydrogen bonding and hydrogen transfer in recent years. Initial chapters present both the experimental and theoretical investigations on the excited-state hydrogen bonding structures and dynamics of many organic and biological chromophores. Following this, several chapters describe the influences of the excited-state hydrogen bonding on various photophysical processes and photochemical reactions, for example: hydrogen bonding effects on fluorescence emission behaviors and photoisomerization; the role of hydrogen bonding in photosynthetic water splitting; photoinduced electron transfer and solvation dynamics in room temperature ionic liquids; and hydrogen bonding barrier crossing dynamics at bio-mimicking surfaces. Finally, the book examines experimental and theoretical studies on the nature and control of excited-state hydrogen transfer in various systems. Hydrogen Bonding and Transfer in the Excited State is an essential overview of this increasingly important field of study, surveying the entire field over 2 volumes, 40 chapters and 1200 pages. It will find a place on the bookshelves of researchers in photochemistry, photobiology, photophysics, physical chemistry and chemical physics.

This book discusses the achievements in the study on the structure of active species being formed at the change of molecule charge or electronic state. It gives a systematic outline of the problem of molecular structure distortions in radical ionic and excited states involving experimental and theoretical material. The text focuses on analyzing the physical reasons for structural distortion occurrences at a model level and also with results of detailed quantum-chemical calculations. The book presents numerous facts on the structural distortions in ions of various types of organic molecules. Data is presented for the first time on distortions in radical ions of polyfluoroaromatics and other conjugated molecules.

The choice of title for this collective volume reflects the desire of the editors and authors to make clear that, while the bulk of the material is concerned with luminescence, other aspects of the excited state have not been excluded. In the five years which have elapsed since the publication of the classical monograph of Konev, a wealth of new information has ap peared on the emission properties of proteins and nucleic acids. Indeed, since new publications in this area appear to be proliferating in a geometric ratio, this may be the last opportunity to provide a comprehensive summary of the field in a book which is not of prohibitive length. This is what we have attempted to do here. While the orientation of each chapter naturally reflects the interests and point of view of the author, there has been a general effort to present .a critical assessment of existing results and interpretations, rather than a compendium of data with minimal comment. Finally, it should be stressed that the rapid evolution of the subject at the time of writing makes it inevitable that the book will age to some degree over the next few years, although this will occur at differing rates for the various chapters. We can only hope that most of the material in this interim summing-up will prove resistant to the erosion of time and provide a solid foundation for further progress.

During the past decade, fluorescence techniques have come to occupy a position of central importance in biochemistry. Such areas as laser techniques, radiation less energy transfer, and nanosecond fluorometry have evolved from esoteric research specialties into standard procedures that are applied routinely to bio chemical problems. Indeed, discussion of the above three areas occupies the greater part of this book. Its level and approach are appropriate for the bio logical or physical scientist who is interested in applying fluorescence techniques, but is not necessarily an expert in this area. The coverage of the literature has, in general, been selective rather than exhaustive. It is likely that what is summarized here will prove resistant to the erosion of time and provide a basis for the future evolution of this rapidly developing area of science. Robert F.
