Book Description
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.

Book Description
Originally published in 1952, this book discusses the contemporary state of research into the Auger Effect and the internal conversion of gamma radiation. Burhop also addresses internal pair production and radiationless transitions in molecular spectra, and photographic images of Auger electrons in action.

Book Description
Filling the gap for a book covering vibronic, nonadiabatic and diabatic couplings as well as radiationless processes in context, this monograph compiles classic and cutting-edge work from numerous researchers into one handy source. Alongside a description of radiationless processes in statistical large molecules and calculational methods for intramolecular distributions, the authors also investigate the nuclear coordinate dependence of matrix elements. Whole chapters are devoted to the mathematical description of the lifetime and decay of a prepared states as well as miscellaneous applications. The text is supplemented by a number of appendices for optimum usability. With its integration of the necessary mathematical rigor, this is primarily intended for graduate students in theoretical physics and chemistry, but is also indispensable reading for those working in molecular physics, physical chemistry and laser physics.

Book Description
Radiationless transitions comprise an important class of physical phenomena occurring in the excited states of molecules. They affect the lifetimes of the ex cited states and govern primary photochemical and photophysical processes. Much effort has been devoted to the understanding of radiationless transi tions. Still, owing to recent advances, the field continues to attract attention. The demand for a book on the theory of these processes naturally arises in at tempting to comprehend a large body of literature, as the famous review article by K. F. Freed and the book by R. Englman do not encompass some issues of current interest. Our intent is to highlight the underlying physical principles and methods in such a way that the book both in its content and its presentation is instruc tive for a wide audience. The basic ideas are treated in simple mathematical terms intelligible to ex perimentalists and to readers unfamiliar with the field. Complicated theoret ical methods are always expounded from first principles, so that a knowledge of quantum mechanics and mathematics at the graduate-student level will enable the reader to easily follow the derivations. Experts will find efficient methods of calculating the transition rates, as well as new applications of quasiclassical methods and fresh treatments of standard problems. Details of measurements are not discussed, and experimental data are only invoked to illustrate the theory.

Book Description
Radiationless Transitions in Polyatomic Molecules treats the dynamics of electronically excited states and the transition probabilities of electronic relaxation processes. Based on a simple and transparent, yet rigorous presentation of the basic physical concepts, the mathematical methods required are developed in detail from first principles and new light shed on the treatment of traditional issues.

Book Description
This graduate-level text presents the fundamental physics of solid-state lasers, including the basis of laser action and the optical and electronic properties of laser materials. After an overview of the topic, the first part begins with a review of quantum mechanics and solid-state physics, spectroscopy, and crystal field theory; it then treats the quantum theory of radiation, the emission and absorption of radiation, and nonlinear optics; concluding with discussions of lattice vibrations and ion-ion interactions, and their effects on optical properties and laser action. The second part treats specific solid-state laser materials, the prototypical ruby and Nd-YAG systems being treated in greatest detail; and the book concludes with a discussion of novel and non-standard materials. Some knowledge of quantum mechanics and solid-state physics is assumed, but the discussion is as self-contained as possible, making this an excellent reference, as well as useful for independent study.

Book Description
This book presents an account of the NATO Advanced Study Institute on "Radiationless Processes," held in Erice, Italy, from November 18 to December 1, 1979. This meeting was organized by the International School of Atomic and Molecular Spectroscopy of the "Ettore Majorana" Centre for Scientific Culture. The objective of the Institute was to formulate a comprehensive treatment of the various processes by which molecules and crystals in excited electronic levels relax nonradiatively to the ground level. A total of 83 participants came from 62 laboratories and 22 nations (Australia, Belgium, Brasil, Canada, Czechoslovakia, France, F. R. Germany, Greece, Hungary, India, Ireland, Israel, Italy, Mexico, The Netherlands, Poland, Portugal, Switzerland, Turkey, United Kingdom, United States, and U.S.S.R.). The secretaries of the Institute were: Velda Goldberg for the scientific aspects and Antonino La Francesca for the administrative aspects of the meeting. Eleven series of lectures for a total of 36 hours were given. Nine "long" seminars and 7 "short" seminars were also presented. In addition, two informal seminars and 2 round-table discussions were held. After an introductory overview of the theory of radiation1ess processes, the Institute dealt firstly with the interaction of electrons with the distribution of vibrational modes in simple molecules, then with the increasingly complex situation found in large lsolated molecules, gnd finally with the coupling of excited electrons with the continuous phonon distribution in insulating solids.

Book Description
Biochemical kinetics refers to the rate at which a reaction takes place. Kinetic mechanisms have played a major role in defining the metabolic pathways, the mechanistic action of enzymes, and even the processing of genetic material. The Handbook of Biochemical Kinetics provides the "underlying scaffolding" of logic for kinetic approaches to distinguish rival models or mechanisms. The handbook also comments on techniques and their likely limitations and pitfalls, as well as derivations of fundamental rate equations that characterize biochemical processes. Key Features * Over 750 pages devoted to theory and techniques for studying enzymic and metabolic processes * Over 1,500 definitions of kinetic and mechanistic terminology, with key references * Practical advice on experimental design of kinetic experiments * Extended step-by-step methods for deriving rate equations * Over 1,000 enzymes, complete with EC numbers, reactions catalyzed, and references to reviews and/or assay methods * Over 5,000 selected references to kinetic methods appearing in the Methods in Enzymology series * 72-page Wordfinder that allows the reader to search by keywords * Summaries of mechanistic studies on key enzymes and protein systems * Over 250 diagrams, figures, tables, and structures
