Book Description
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.

Book Description
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.

Book Description
This unified treatment introduces upper-level undergraduates and graduate students to the concepts and methods of modern molecular spectroscopy and their applications to quantum electronics, lasers, and related optical phenomena. Starting with a review of the prerequisite quantum mechanical background, the text examines atomic spectra and diatomic molecules, including the rotation and vibration of diatomic molecules and their electronic spectra. 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.

Book Description
Single Molecule Spectroscopy is one of the hottest topics in today's chemistry. It brings us close to the the most exciting vision generations of chemists have been dreaming of: To observe and examine single molecules! While most of chemistry deals with myriads of molecules, this books presents the latest developments for the detection and investigation of single entities. Written by internationally renowned authors, it is a thorough and comprehensive survey of current methods and their applications.

Book Description
This third edition of Peter Bernath's successful Spectra of Atoms and Molecules is designed to provide advanced undergraduates and graduate students a working knowledge of the vast field of spectroscopy. Also of interest to chemists, physicists, astronomers, atmospheric scientists, and engineers, this volume emphasizes the fundamental principles of spectroscopy with the primary goal of teaching the interpretation of spectra. Features include a presentation of group theory needed to understand spectroscopy, detailed worked examples and a large number of excellent problems at the end of each chapter. Prof. Bernath provides a large number of diagrams and spectra which have been specifically recorded for this book. Molecular symmetry, matrix representation of groups, quantum mechanics, and group theory are among the topics covered; atomic, rotational, vibrational, electronic and Raman spectra are analyzed. Bernath's clear treatment of the confusing topic of line strengths as needed for quantitative applications is featured. This much-needed new edition has been updated to include the 2010 CODATA revision of physical constants, and a large number of corrections and clarifications. Responding to student requests, the main new feature is the addition of detailed worked examples in each chapter. Spectra of Atoms and Molecules, 3e will help demystify spectroscopy by showing readers the necessary steps in a derivation, as well as the final result.
