Chemical and Biological Applications of Lasers, Volume V focuses on the laser applications in photochemistry and spectroscopy. This book examines the spectroscopic detection of single atoms and explores the purification of industrial chemicals. Organized into seven chapters, this volume starts with an overview of the methods developed for laser detection of single atoms, including fluorescence, photoionization, photodeflection, and their combinations. This text then discusses the methods of high resolution spectroscopy, which provide detailed information on molecular structure and reaction kinetics studies. Other chapters review several laser photodissociation studies, which explain dissociation dynamics. This book discusses as well the possibilities for selective photochemical reactions and examines the potential of lasers for practical application in chemical processing. The final chapter considers the various metals that can undergo a photochemical change in oxidation state in ordinary solvents. This book is a valuable resource for physicists, chemists, electrochemists, photochemists, electrical engineers, and chemical engineers.
Chemical and Biochemical Applications of Lasers, Volume III presents the fundamental principles and methods of selective photophysical and photochemical processes. The book discusses isotopic separations and related research for each eight classes of laser methods, and their applications in chemistry, biology, and materials science. The experimental results on multiphoton infrared processes and their theoretical interpretation are likewise thoroughly discussed and described. Organic and inorganic chemists, physical chemists, and optical physicists will find the text a valuable reference material.
This book provides an introduction on applications of lasers in Chemistry. It describes laser as a tool for chemistry, the consideration involved in describing a laser beam and what happens to beam as it is propagated through a gas. The book is useful for graduates and advanced undergraduates.
Chemical and Biochemical Applications of Lasers, Volume IV focuses on the practical applications of standard commercial laser systems. This book examines the structural studies of DNA by fluorescence microscopy and discusses photochemistry and structural spectroscopy. Organized into eight chapters, this volume starts with an overview of a few cases of laser-induced fluorescence studies of biological molecules. This text then examines the sharp fluorescence spectra of complex molecules in solids that are obtained when a narrow-band laser selectively excites molecules in particular sites. Other chapters describe the theory and application of resonance Raman spectroscopy to various biological systems. This book provides as well a thorough treatment of coherent anti-Stokes Raman spectroscopy and its application in combustion diagnostics and analytical chemistry. The final chapter explores laser control of the sequential photochemical reaction of the drug psoralen with the two strands of the DNA double helix. Physicists, chemists, electrochemists, and chemical engineers will find this book useful.
The Fifth International Conference on Laser Spectroscopy or VICOLS, was held at Jasper Park Lodge, in Jasper, Canada, June 29 to July 3, 1981. Following the tradition of the previous conferences in Vail, Megeve, Jackson Lake, and Rottach-Egern, it was hoped that VICOLS would provide an opportunity for act ive scientists to meet in an informal atmosphere for discussions of recent developments and applications in laser spectroscopy. The excellent conference facilities and remote location of Jasper Park Lodge in the heart of the Canadian Rockies, amply fulfilled these expectations. The conference was truly international, with 230 scientists from 19 countries participating. The busy program of invited talks lasted four days, with two evening sessions, one a panel discussion on Rydberg state spectro scopy, the other a lively poster session of approximately 60 post-deadline papers. We wish to thank all of the participants for their outstanding contribu tions and for preparation of their papers, now available to a wider audience. Our thanks go to the members of the International Steering Committee for their suggestions and recommendations. We are especially pleased to have held this conference under the auspices of the International Union of Pure and Applied Physics. VICOLS would not have been possible with out the financial support of the Natural Sciences and Engineering Research Council of Canada, and the Office of Naval Research and Air Force Office of Scientific Research of the United States* of America.
Based on a symposium on lasers, molecules, and methods held at the Los Alamos Center for Nonlinear Studies held in July 1986. Contributors present recent advances in theoretical and experimental research on a diversity of dynamical and optical phenomena resulting from the interactions of laser beams with molecules. They describe the predictive results of sophisticated mathematical models, the equipment involved in experiments, and reveal new insights into molecular structure and behavior.
The laser as a radiation source with temporal and spatial coherence has made a tremendous impact in the different fields of science. As a result, new and exciting research has been developing allover the world. Laser spectro scopy shares a large fraction of this research, and in the last decade nu merous books and monographs have been published on this subject. Most of these books and monographs contain the work done in the physics community. Very few books represent the advances made in laser chemistry, a field that is flourishing and whose future is indeed very exciting. It was felt that a meeting that focused on the important questions being asked in the chemistry community, and on new and possible directions in laser chemistry, was needed. This three-day conference, held at the California Institute of Technology, Pasadena, California, on March 20-22, 1978, covered five important areas in laser chemistry: Laser-induced chemistry, picosecond processes and techniques, nonlinear optical spectroscopy and dephasing processes, multiphoton exci tation in molecules, and molecular dynamics by molecular beams.
Over the past few years, there has been a growing awareness of the vibratio nal properties of solid surfaces and adsorbates due to a steady growth in the number of experimental techniques which have evolved with sufficient resolution and surface sensitivity. An understanding of the surface vibratio nal modes is of fundamental importance in many areas of the physics and chemistry of surfaces, most notably in the field of heterogeneous catalysis on metals and alloys. The present volume derives from a one day meeting of invited lectures, held under the auspices of the Thin Films and Surfaces Section of the Insti tute of Physics in the Cavendish Laboratory, University of Cambridge, 13 December 1979. The object was to bring together specialists from various diverse fields who would examine the wide variety of methods currently avail able for studying surface adsorbate vibrations. Since these methods cover several scientific disciplines, it was subsequently felt that it would be useful to provide a permanent record of the talks as a source lor future reference by workers in what is rapidly becoming an expanding field of',inter est in an increasing number of laboratories. The contributions, however, are not in any way meant to constitute exhaustive reviews.
This Conference on biomedical applications of. lasers ~Ias organized by the Quantum Electronics Divisional Board of the European Physical Society (E.P.S.) and held at the Villa of Poggio Imperiale in Florence, September 3-6, 1979. As kno~m, laser surgery (especially microsurgery and endoscopic photo coagulation) has recently made important progress, and the field is expand i ng rapidly. Very significant applications of lasers have also been achieved in Bi ology during recent years (cell microsurgery, cell counting and sorting, cytofluorimeter devices, etc.) and the potential of laser techniques in this field is nO~1 sufficiently well establ ished. A new class of applications of laserradiJtion in Medicine has recently been made possible by important results obtained with low intensity (non coagulative) visible lasers, such as photodynamic therapy of tumors. At the same time important branches of Medicine, where light effects are studied and optical techniques are presently used for a certain number of clinical applications, such as dermatology and pediatry, appear to be still in their infancy as far as the proper use of optical radiation and techniques, and the understanding of fundamental photoinduced biological processes are con cerned. Moreover, laser photobiology appears a very promising field for the investigation of fundamental processes at the biomolecular level.
