Energy Transfer Parameters of Aromatic Compounds focuses on the mechanisms underlying intramolecular and intermolecular electronic energy transfer in aromatic compounds, with emphasis on dipole-dipole interactions. The compounds covered range from benzene and toluene to phenyl ether, aniline, phenol, styrene, indole, and dibenzofuran. This book is comprised of eight chapters and begins with an overview of the transfer of electronic energy in reactions in radiation, photochemistry, physics, and biology. A short historical sketch is also provided to give the reader a proper perspective of some of the concepts. Material diffusion or collisional transfer, energy migration, and solvent and host effects are explained, along with phenomenological processes such as singlet-singlet transfer and sensitized fluorescence. The discussion then turns to intermolecular and intramolecular electronic energy transfer, paying particular attention to radiation and radiationless transfer, conjugated and nonconjugated chromophores, and rare-earth chelates. Studies related to electronic energy transfer are also presented. The final chapter includes tables listing compounds in their numbered sequence. The spectroscopic data are taken on solutes that are soluble in cyclohexane. This monograph will be of interest to organic chemists and physicists.

Photochemical processes form the basis of life. Energy transfer through photons also underlies a wide range of phenomena ranging from the motion of atoms and molecules to the assembly of systems of molecules, such as polymers, Langmuir-Blodgett films and even liquid crystals.Photochemical Processes in Organized Molecular Systems provides an overview of recent photochemical investigations of systems of molecules. The book is divided into four parts: the first two deal with current progress on the understanding of photoinduced chemical processes, the third and fourth chapter deal with the photochemistry of organized molecular systems including polymers, micelles and liquid crystals.This book should be studied by all who want to know more about this promising field of photochemical research, and about the fascinating processes that light can bring about.

This book introduces the physics and chemistry of plastic scintillators (fluorescent polymers) that are able to emit light when exposed to ionizing radiation, discussing their chemical modification in the early 1950s and 1960s, as well as the renewed upsurge in interest in the 21st century. The book presents contributions from various researchers on broad aspects of plastic scintillators, from physics, chemistry, materials science and applications, covering topics such as the chemical nature of the polymer and/or the fluorophores, modification of the photophysical properties (decay time, emission wavelength) and loading of additives to make the material more sensitive to, e.g., fast neutrons, thermal neutrons or gamma rays. It also describes the benefits of recent technological advances for plastic scintillators, such as nanomaterials and quantum dots, which allow features that were previously not achievable with regular organic molecules or organometallics.

In 1980 the New York Academy of Sciences sponsored a three-day conference on luminescence in biological and synthetic macromolecules. After that meeting, Professor Frans DeSchryver and I began to discuss the possibility of organizing a different kind of meeting, with time for both informal and in-depth discussions, to examine certain aspects of the application of fluorescence and phosphorescence spectroscopy to polymers. Our ideas developed through discussions with many others, particularly Professor Lucien Monnerie. By 1983, when we submitted our proposal to NATO for an Advanced Study Institute, the area had grown enormous ly. It is interesting in retrospect to look back on the points which emerged from these discussions as the basis around which the scientific program would be organized and the speakers chosen. We decided early on to focus on applications of these methods to provide information about polymer molecules and polymer systems: The topics would all relate to the conformation and dynamics of macromolecules, or to the morphology of polymer-containing systems. Another important decision was to expand the scope of the ASI to include certain photochemical techniques, parti cular ly laser flash pho to lys is. These appl icat ions were at the time quite new, but full of promise as important sources of information about polymers.

At the time that the editors conceived the idea of trying to organize the meeting on which the contents of this volume are based and which became, in March 1980, a NATO Advanced Study Institute, the techniques of time-resolved fluorescence spectroscopy, in both the nanosecond and sub-nanosecond time-domains, might reasonably have been said to be coming of age, both in their execution and in the analysis and interpretation of the results obtained. These techniques, then as now, comprised mainly a number of pulse methods using laser, flash-lamp or, most recently, synchrotron radiation. In addition, significant developments in the more classical phase approach had also rendered that method popular, utilizing either modulation of an otherwise continuous source or, again recently, the ultra-rapid pulse rate attainable with a synchrotron source. In general terms, time-resolved fluorescence studies are capable, under appropriate conditions, of supplying direct kinetic information on both photophysics and various aspects of molecular, macromolecular and supramolecular structure and dynamics. The nanosecond and sub-nanosecond time-scales directly probed render these techniques particularly appropriate in studying relaxation and fluctuation processes in macromolecules, particularly biopolymers (e. g. proteins, nucleic acids), in supramolecular assemblies such as cell membranes, and in a variety of relatively simpler model systems.

In view of the rapid growth in both experimental and theoretical studies of multi-photon processes and multi-photon spectroscopy of atoms, ions and molecules in chemistry, physics, biology, materials science, etc., it is desirable to publish an advanced series containing review papers that can be read not only by active researchers in these areas, but also by those who are not experts but who intend to enter the field. The present series attempts to serve this purpose. Each review article is written in a self-contained manner by the experts in the area, so that the reader can grasp the knowledge without too much preparation.

The goals of the science of photobiology can be divided into four categories: to develop (I) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and physicists; because photobiology is a truly multidisciplinary science. While a multidis ciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for theoretical or practical use. Photochemical and Photobiological Reviews continues to provide in depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger scientists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate. Since it is important that this review series remain responsive to the needs of photochemists and photobiologists, the Editor would value com ments and suggestions from its readers.
