Available in PDF, EPUB and Kindle. Book excerpt: Complément naturel de la spectroscopie atomique qui nous livre une grande partie du secret des atomes, la spectroscopie moléculaire connaît depuis plusieurs décennies des avancées spectaculaires dans des domaines aussi divers et variés que l’astrophysique, la physique planétaire, l’industrie des matériaux ou les sciences biomédicales. Grâce à des études de plus en plus détaillées de tous les domaines spectraux compris entre l’ultraviolet et les microondes, la spectrométrie moléculaire a accru de manière considérable son impact sur de multiples domaines qui relèvent des sciences pures et appliquées. Le but de la présente synthèse est, au départ de considérations historiques, de décrire l’état actuel de cette science dont les méthodes apparaissent de plus en plus comme un outil indispensable à de multiples disciplines. La première partie du livre est consacrée à une description des spectres moléculaires et à une introduction à la symétrie et à la théorie des groupes. Considérant tour à tour les molécules diatomiques puis les molécules plus complexes, l’ouvrage traite alors successivement des phénomènes de rotation et de vibration dans les molécules avant d’envisager les transitions électroniques. Une attention particulière est accordée aux techniques mises en oeuvre en spectrométrie ultraviolette et visible, en spectroscopie infrarouge et pour l’étude des phénomènes de fluorescence. Enfin les applications de la spectroscopie moléculaire à l’astrophysique sont brièvement évoquées. Synthèse actuelle, détaillée mais pas trop technique de la spectrométrie moléculaire, tel peut être décrit le contenu de cet ouvrage.

Download or read book Molecular Symmetry and Spectroscopy written by Philip Bunker and published by Elsevier. This book was released on 2012-12-02 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Symmetry and Spectroscopy deals with the use of group theory in quantum mechanics in relation to problems in molecular spectroscopy. It discusses the use of the molecular symmetry group, whose elements consist of permutations of identical nuclei with or without inversion. After reviewing the permutation groups, inversion operation, point groups, and representation of groups, the book describes the use of representations for labeling molecular energy. The text explains an approximate time independent Schrödinger equation for a molecule, as well as the effect of a nuclear permutation or the inversion of E* on such equation. The book also examines the expression for the complete molecular Hamiltonian and the several groups of operations commuting with the Hamiltonian. The energy levels of the Hamiltonian can then be symmetrically labeled by the investigator using the irreducible representations of these groups. The text explains the two techniques to change coordinates in a Schrödinger equation, namely, (1) by using a diatomic molecule in the rovibronic Schrödinger equation, and (2) by a rigid nonlinear polyatomic molecule. The book also explains that using true symmetry, basis symmetry, near symmetry, and near quantum numbers, the investigator can label molecular energy levels. The text can benefit students of molecular spectroscopy, academicians, and investigators of molecular chemistry or quantum mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: The spectra of molecules containing more than one atom are necessarily of single atoms. They are correspondingly much more complex than those richer, not only in the number of spectral lines, but also in qualitatively different phenomena which do not have any counterpart in single atoms. Historically, molecular spectra have revealed much fundamental phy sics, such as the connection between nuclear spin statistics. They have pro vided models of physical systems which have been useful in quite different areas, such as particle physics. Most especially, molecular spectra are of fundamental importance in understanding chemical bonding. They reveal not only bond lengths but also the strength of the bonding potential between atoms. Moreover, these measurements are obtained for electronic excited states, as well as for the ground state, and for unstable short-lived molecules. In recent years, tunable lasers have provided powerful tools for the measurement and analysis of molecular spectra. Even before that, molecules were being used in lasers, most notably in the carbon dioxide laser, which finds many industrial applications.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular Spectroscopy: Modern Research, Volume III is a collection of papers presented at the 40th Annual Molecular Spectroscopy Symposium, held at the Ohio State University. The contributors of this seven-chapter text cover the significant advances in molecular spectroscopic research and their application in chemistry. Chapters 1 and 2 discuss first the higher-order vibration-rotation interactions in molecules and then present formulas and an insight into the direction being taken in theoretical pursuits. Chapter 3 provides an extensive compilation of published intensity and collision broadening parameters derived from infrared spectra. This chapter also contains a detailed discussion using consistent notation of some of the methods commonly applied to extract such information from laboratory spectra. Chapter 4 examines a variety of laser systems and their application in investigations involving triatomic free radicals and ions, while chapter 5 considers the developments in the microwave spectroscopic studies on nonpolar molecules when their symmetry is reduced by isotopic substitution. Chapter 6 emphasizes the quasi-linear molecular problem to develop an appreciation of the symptoms of quasi-linearity and theoretical treatments thereof. This chapter also examines the increasing role of highly resolved spectra in the interpretation of various large-amplitude motions in molecules. Lastly, Chapter 7 describes the electric multipolar moments of hydrogen and its isotopes. Spectroscopists, chemists, and researchers will find this work invaluable.

Download or read book Infrared Spectroscopy of Symmetric and Spherical Top Molecules for Space Observation Volume 2 written by Pierre-Richard Dahoo and published by John Wiley & Sons. This book was released on 2021-09-15 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, Volume 4 in the series, is dedicated to the relationship between laboratory spectroscopy, recording ever-more-complex spectra using increasingly powerful instruments benefiting from the latest technology, and the development of observation using instruments that are embedded in mobile probes or nanosatellites. The theoretical models described in Volumes 1, 2 and 3 are used in this volume, applying the cumulant theorem in the mean-field theory framework to interpret the near and mid-infrared spectra of symmetric top molecules, such as ammonia (NH3) and spherical molecules, such as methane (CH4). These molecules can be isolated in their gaseous form or subjected to the environmental constraints of a nano-cage (a substitution site, clathrate, fullerene or zeolite) or surfaces. These methods are not only valuable in the fields of environmental sciences, planetology and astrophysics, but also fit into the framework of data processing and the concept of Big Data.

A discussion of rudimentary group theory advances to considerations of the rotational spectra of polyatomic molecules and their vibrational and electronic spectra; molecular beams, masers, and lasers; and a variety of forms of spectroscopy, including optical resonance spectroscopy, coherent transient spectroscopy, multiple-photon spectroscopy, and spectroscopy beyond molecular constants. The text concludes with a series of useful appendixes.
Download or read book Spectroscopy of Condensed Media written by C.H. Wang and published by Elsevier. This book was released on 2012-12-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy of Condensed Media: Dynamics of Molecular Interactions discusses the use of molecular spectroscopy (including nuclear magnetic resonance [NMR] and nonlinear optical spectroscopy) in dynamic processes in condensed molecular systems. The book reviews relationship between transition probability and the time-correlation function of an isotropic electric dipole system, linear-response theory, and light scattering resulting from the translational motion of molecules in fluids. The text describes molecular rotation, theories of angular momentum, nuclear magnetic resonance, and spontaneous and coherent Raman effects. Closely related with the Raman and Brillouin scattering are vibrational dephasing, relaxation processes, and dynamics of phase transition solids. The book highlights the advantages of using NMR and also explains the basic concepts, such as local field, spin temperature, and effective Hamiltonians, that are employed in interpreting NMR experiments. The investigator can use nonlinear optical spectroscopy to study condensed matter. The text also cites two methods in which the investigator can control the time-dependent average Hamiltonian by (1) manipulating the intensity, timing, phase of the pulses, or (2) by sample spinning. The book is intended for advanced graduate students in physical chemistry that will equally benefit both investigators and scientists involved in physics research.
