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
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
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.

Book Description
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.
