This book was released on 1998 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large variety of nonlinear spectroscopic methods have so far been developed and applied to studies of molecular structure and dynamics. Some of these methods utilize complex techniques, making it difficult to understand the underlying principles. Furthermore, most of these methods are referred to by nicknames or acronyms, which keeps them shrouded in mystery for most non–specialists who are thereby discouraged from mastering and applying the methods to molecular systems. Under these circumstances it was judged appropriate and timely to overview those nonlinear spectroscopic methods which are currently particularly useful for studies of molecular structure and dynamics. Thus, the Commission on Molecular Structure and Spectroscopy of the International Union of Pure and Applied Chemistry decided to publish a book, intended to provide an introduction to nonlinear spectroscopy for non–specialists.

This book was released on 1988-01-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Authoritative and clearly written."—Applied Optics The direct observation of short-lived free radicals and the consequent study of their structure and reactions have led to important developments in almost every branch of chemistry as well as in other areas. This volume by a Nobel laureate offers an excellent introduction to the essentials of molecular spectroscopy. The introductory chapter discusses experimental methods and illustrates the observed spectra of various molecules and free radicals. Subsequent chapters explore rotational, vibrational, and electronic energy levels of diatomic molecules and ions; radiative transitions; linear and nonlinear polyatomic radicals and ions; continuous and diffuse spectra; predissociation and pre-ionization; and recombination. The well-illustrated text features more than 100 figures and spectra. A distilled version of the author's monumental three-volume study, Molecular Spectra and Molecular Structure, it constitutes a superb resource for anyone wishing a concise but complete treatment of the fundamentals of molecular spectroscopy.

This book was released on 2013-11-21 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an account of the course "Nonlinear Spectroscopy of Solids: Advances and Applications" held in Erice, Italy, from June 16 to 30, 1993. This meeting was organized by the International School of Atomic and Molecular Spectroscopy of the "Ettore Majorana" Centre for Scientific Culture. The purpose of this course was to present and discuss physical models, mathematical formalisms, experimental techniques, and applications relevant to the subject of nonlinear spectroscopy of solid state materials. The universal availability and application of lasers in spectroscopy has led to the widespread observation of nonlinear effects in the spectroscopy of materials. Nonlinear spectroscopy encompasses many physical phenomena which have their origin in the monochromaticity, spectral brightness, coherence, power density and tunability of laser sources. Conventional spectroscopy assumes a linear dependence between the applied electromagnetic field and the induced polarization of atoms and molecules. The validity of this assumption rests on the fact that even the most powerful conventional sources of light produce a light intensity which is not strong enough to equalize the rate of stimulated emission and that of the experimentally observed decay. A different situation may arise when laser light sources are used, particularly pulsed lasers. The use of such light sources can make the probability of induced emission comparable to, or even greater than, the probability of the observed decay; in such cases the nonlinearity of the response of the system is revealed by the experimental data and new properties, not detectable by conventional spectroscopy, will emerge.

Book excerpt: In linear optical spectroscopy, atomic and molecular structure is probed by light. The intensity, frequencies, and spectral width observed in the signal output from a sample--whether by reflection, transmission, absorption or scattering--reveal clues of energy transitions, and hence information about the electronic, vibrational, and other motional and structural aspects at the molecular level. Typically, the probing photons induce transitions between energy levels characteristic of the sample's molecules. Through analysis of the spectral output, the relative pattern of molecular levels can be reconstructed. Nonlinear optical spectroscopy on the other hand, rather than acting just as a probe, strongly perturbs the system. The strong optical electronic fields reorient the molecule's spatial positions, distort electron clouds, and excite uncharacteristic or forbidden transitions.
Download or read book Principles of Nonlinear Optical Spectroscopy written by Shaul Mukamel and published by Oxford University Press on Demand. This book was released on 1999 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents a systematic and unifying viewpoint for a wide class of nonlinear spectroscopic techniques in time domain and frequency domain. It is directed towards active researchers in physics, optics, chemistry, and materials science, as well as graduate students who enter this complex and rapidly developing field. Nonlinear optical interactions of laser fields with matter provide powerful spectroscopic tools for the understanding of microscopic interactions and dynamic processes. One of the major obstacles facing researchers in this field, however, is the flood of experimental techniques and terminologies, which create a serious language barrier. The general microscopic correlation function approach to the nonlinear optical response developed in this book is essential for understanding the relationships among different techniques and a comparison of their information content, the design of new measurements, and for a systematic comparison of the optical response of different systems such as dyes in solutions, atoms and molecules in the gas phase, liquids, molecular aggregates and superlatives, and semiconductor nanostructures. The approach is based on formulating the nonlinear response by representing the state of matter by the density matrix and following its evolution on Liouville space. Current active research areas such as femtosecond time-domain techniques, semi-classical and wave-packet dynamics, pulse shaping, pulse locking, exciton confinement, and the interplay of electronic, nuclear and field coherence are emphasized. The material has been developed from the author's highly successful interdisciplinary course at the University of Rochester attended by science and engineering graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: “I have endeavoured to give a presentation which is readable by the beginner in the field and also will be useful to those who do or want to do research work in this field. In order to assist the former, I have frequently made use of small type for those sections that are not necessary for an understanding of the fundamentals. For the benefit of those working in the field, numerous references to original papers have been included. “A satisfactory presentation of molecular spectra and molecular structure is nowadays not possible without treating thoroughly, apart from the empirical results, the theoretical background also. Therefore, I have included as much of the theory of molecular spectra as is possible without going into the more difficult mathematical details. A large number of diagrams, graphical representations of eigenfunctions and potential curves, as well as energy level diagrams, serve to illustrate and to explain the theory. On the other hand, I have added numerous carefully selected spectrograms of bands and band systems (some of which have been taken specially for this purpose) in order to give an accurate idea of the experimental material that forms the basis of the developments.

Available in PDF, EPUB and Kindle. Book excerpt: "The application of spectroscopic and diffraction techniques to the study of molecules an ions has revolutionized the processes of analysis and structure determination, thus profoundly affecting the development of chemistry and molecular biology. These modern approaches increasingly find their place in 'A' level and National Certificate syllabuses, as well as at an early stage in degree level courses. Emphasis is placed here on the results which can be obtained by the application of these techniques- that is, how the identity of a compound may be obtained and how its detailed molecular structure can be determined. Mass spectrometry, infra-red and ultra-violet spectroscopy, nuclear magnetic resonance spectroscopy and the diffraction methods are all described and their uses are illustrated. Essential physical principles (such as the quantum theory, the wave nature of radiation) are introduced, but mathematical content has been kept to a minimum."- Publisher.

Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.
