Available in PDF, EPUB and Kindle. Book excerpt: Multiphoton Spectroscopy of Molecules deals with the fundamental theory, methods, and basic results in multiphoton spectroscopy research made possible by using powerful lasers. This book reviews the progress made in visible and UV multiphoton spectroscopy, including the characteristic properties of multiphoton transitions. Certain theoretical methods such as the time-dependent perturbation, density matrix, Green's function, and susceptibility methods, can point to multiphoton transitions in a molecular system, beginning from first principles. This text also describes the technique in detecting two- or three-photon absorption by multiphoton ionization of molecules. A type of optical mass spectroscopy combining spectroscopic information derived from multiphoton absorption with mass spectrometric information has provided interesting results. This book also discusses the polarization behavior of two-photon absorption processes of molecules. Monson, McClain, and Nascimento have investigated the polarization dependence of the two-photon absorption cross section of randomly oriented, nonrotating molecules. his text also presents the spectroscopic results of excited states confirmed when the multiphoton techniques is applied, as well as some experimental and theoretical approaches related to multiphoton spectroscopy of molecules. Nuclear scientists and physicists, atomic researchers, molecular physicists, and academicians in the field of quantum mechanics or physical chemistry will greatly appreciate the book.

Download or read book Topics in Fluorescence Spectroscopy written by Joseph R. Lakowicz and published by Springer Science & Business Media. This book was released on 2006-04-18 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence spectroscopy continues its advance to more sophisticated methods and applications. As one looks over the previous decades, its appears that the first practical instruments for time-resolved measurements appeared in the 1970’s. The instrumentation and analysis methods for time-resolved fluorescence advanced rapidly throughout the 1980’s. Since 1990 we have witnessed a rapid migration of the principles of time-resolved fluorescence to cell biology and clinical appli- tions. Most recently, we have seen the introduction of multi-photon excitation, pump-probe and stimulated emission methods for studies of biological mac- molecules and for cellular imaging. These advanced topics are the subject of the present volume. Two-photon excitation was first predicted by Maria Goppert-Mayer in 1931, but was not experimentally observed until 1961. Observation of two-photon excitation required the introduction of lasers which provided adequate photon density for multi-photon absorption. Since the early observations of two-photon excitation in the 1960s, multi-photon spectroscopy has been limited to somewhat exotic applications of chemical physics, where it is used to study the electronic symmetry of small molecules. Placing one’s self back in 1980, it would be hard to imagine the use of multi-photon excitation in biophysics or cellular imaging.

Download or read book Advanced Concepts in Fluorescence Sensing written by Chris D. Geddes and published by Springer Science & Business Media. This book was released on 2005-06-28 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, fluorescence has become the dominant tool in biotechnology and medical imaging. These exciting advances have been underpinned by the advances in time-resolved techniques and instrumentation, probe design, chemical / biochemical sensing, coupled with our furthered knowledge in biology. Complementary volumes 9 and 10, Advanced Concepts of Fluorescence Sensing: Small Molecule Sensing and Advanced Concepts of Fluorescence Sensing: Macromolecular Sensing, aim to summarize the current state of the art in fluorescent sensing. For this reason, Drs. Geddes and Lakowicz have invited chapters, encompassing a broad range of fluorescence sensing techniques. Some chapters deal with small molecule sensors, such as for anions, cations, and CO2, while others summarize recent advances in protein-based and macromolecular sensors. The Editors have, however, not included DNA or RNA based sensing in this volume, as this were reviewed in Volume 7 and is to be the subject of a more detailed volume in the near future.
Download or read book Molecular Imaging written by Ammasi Periasamy and published by Elsevier. This book was released on 2011-04-28 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detection and measurement of the dynamic interactions of proteins within the living cell are critical to our understanding of cell physiology and pathophysiology. With FRET microscopy and spectroscopy techniques, basic and clinical scientists can make such measurements at very high spatial and temporal resolution. But sources of background information about these tools are very limited, so this book fills an important gap. It covers both the basic concepts and theory behind the various FRET microscopy and spectroscopy techniques, and the practical aspects of using the techniques and analyzing the results. The critical tricks for obtaining a good FRET image and precisely quantitating the signals from living specimens at the nanomolecular level are explained. Valuable information about the preparation of biological samples used for FRET image analysis is also provided. The methods covered include different types of microscopy systems and detectors (wide-field, confocal, multi-photon) as well as specialized techniques such as photobleaching FRET, FLIM-FRET microscopy, spectral imaging FRET, single molecule FRET, and time and image correlation spectroscopy. Starting from the basics, the chapters guide readers through the choice of probes to be used for FRET experiments and the selection of the most suitable experimental approaches to address specific biological questions. Up-to-date, consistently organized, and well-illustrated, this unique book will be welcomed by all researchers who wish to use FRET microscopy and spectroscopy techniques.
Download or read book Multiphoton Processes written by P. Lambropoulos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this volume represent the invited papers delivered at the 3rd International Conference on Multiphoton Processes (ICOMP III) held in Iraklion, Crete, Greece, September 5-11, 1984. The invited papers at a conference like ICOMP cannot possibly cover the whole field which has grown to immense proportions in recent years, overlapping with such diverse areas as atomic and molecular spectroscopy, plasma physics, nonlinear optics, quantum optics, etc. We believe these contributions represent that part of the research activity which has been attracting the most interest in the past year or so, as well as reviews of some of the more established topics. Even within this scope, and given the confines imposed by the fi nite duration of a conference, important and timely topics are inevitably left out. But then, there will be ICOMP IV. The collection of articles in this volume, combined with extensive ref erences to related work given by the authors, should provide an introduc tion to the major problems of the field and its state of the art. The chapters have been arranged according to thematic proximity, beginning with atoms, and continuing on with molecules and surfaces. This classi fication, however, would not cover all the subject matter even within the limited scope of the conference and of this volume.

Download or read book Green Fluorescent Protein written by Martin Chalfie and published by John Wiley & Sons. This book was released on 2005-11-18 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of the gene for green fluorescent protein (GFP), derived from jellyfish, this protein that emits a green glow has initiated a revolution in molecular biosciences. With this tool, it is now possible to visualize nearly any protein of interest in any cell or tissue of any species. Since the publication of the first edition, there have been tremendously significant technological advances, including development of new mutant variants. Proteins are now available in yellow and blue, and Novel Fluorescent Proteins (NFPs) have expanded their utility in developing biosensors, biological markers, and other biological applications. This updated, expanded new edition places emphasis on the rise of NFPs, including new chapters on NFP properties with detailed protocols, applications of GFPs and NFPs in industry research, and biosensors. This book provides a solid theoretical framework, along with detailed, practical guidance on use of GFPs and NFPs with discussion of potential pitfalls. The expert contributors provide real examples in showing how to tailor GFP/NFP to specific systems, maximize expression, and enhance detection.
Download or read book Nonlinear Laser Spectroscopy written by V. S. Letokhov and published by Springer. This book was released on 2014-04-18 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laser as a source of coherent optical radiation has made it possible to investigate nonlinear interaction of optical radiation with atoms and mole cules. Its availability has given rise to new research fields, such as non linear optics, laser spectroscopy, laser photochemistry, that lie at the boundary between quantum electronics and physical optics, optical spectros copy and photochemistry, respectively. The use of coherent optical radiation in each of these fields has led to the discovery of qualitatively ne\~ effects and possibilities; in particular, some rather subtle effects of interaction between highly monochromatic light and atoms and molecules, in optical spec troscopy, have formed the bases for certain methods of so-called nonlinear, laser Doppler-free spectroscopy. These methods have made it possible to in 5 6 crease the resolution of spectroscopic studies from between 10 and 10 , lim 11 ited by Doppl er 1 i ne broadeni ng up, to about 10 ; at present some 1 abor atories are developing new techniques that have even higher resolution. The discovery and elaboration of the methods of nonlinear laser spectroscopy have resulted largely from contributions by scientists from many countries, in particular from the USA (Massachusetts Institute of Technology, Stanford Uni versity, National Bureau of Standards in Boulder, Harvard University, etc. ), the USSR (P. N. Levedev Institute of Physics, Institute of Semiconductor Phys ics in Novosibirsk, Institute of Spectroscopy, etc.

Download or read book Laser Spectroscopy of Highly Vibrationally Excited Molecules written by Vladilen Stepanovich Letokhov and published by CRC Press. This book was released on 2021-07-28 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser spectroscopy has been perfected over the last fifteen years to become a precise tool for the investigation of highly vibrationally excited molecules. Intense infrared laser radiation permits both the multiple-photon resonant excitation and the dissociation of polyatomic molecules. In this book, the latest results of some of the foremost Soviet researchers are published for the first time in the West. Laser Spectroscopy of Highly Vibrationally Excited Molecules contains a comprehensive study of both the experimental and theoretical aspects of the basic photophysical interactions that occur in these processes. The book first focuses on the nonlinear interaction between the resonant vibrational mode and the intense infrared field and then examines the nonlinear interaction between the vibrational modes themselves due to anharmonicity. These interrelated processes determine all the characteristics of polyatomic molecules in an infrared field. The book also discusses related phenomena such as spectra broadening, optical resonance, photon echoes, and dynamical chaos. It includes examples of multiple-photon resonant excitation such as the excitation of OsO4 by CO^O2 laser radiation, which is detected by the visible luminescence that results. This book will be of great interest to researchers and postgraduate students in infrared laser spectroscopy and the laser chemistry of molecules and applications of isotope separation.
