Download or read book Essentials of Modern Physics Applied to the Study of the Infrared written by Armand Hadni and published by Elsevier. This book was released on 2016-07-29 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essentials of Modern Physics Applied to the Study of the Infrared covers topics about the essentials of modern physics. The book starts with the situation of research into the infrared and the problems to which it gives rise, and then discusses instrumentation in the infrared: optics, sources, receivers and electronics. The book describes the interaction between the infrared and matter within the framework of Lorentz's general theory and in the particular case of solids using Born's theory and introducing the notion of phonons. The region of the electromagnetic spectrum and the developments in science and industry, including X-ray analysis, molecular beam experiments, radio, and television are considered. The book tackles the sources of infrared as well as infrared detectors. The text will be useful to physicists, engineers, and laboratory technicians.

This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared Astronomy is a relatively new subject but it has already radically altered our ideas about astronomical sources. Recent progress in this subject is the result of improved detection techniques, particularly the use of detectors at liquid helium temperatures. Unfortunately, the terrestrial atmosphere greatly restricts Infrared astronomers by allowing them to detect radiation only in narrow transmission win dows and by presenting a foreground emission which limits the faintness of observable sources. It is only from aircraft or balloon altitudes that we can begin to observe faint sources over the complete range of wavelengths between the visible and the radio regions. Few such observations have yet been made and none from satellites, although the latter vehicle will offer complete freedom from atmospheric effects. New developments and intermediate steps will be required before the ultimate aim of flying in space can be achieved. It is not surprising therefore that the Fifth Eslab/Esrin Symposium should deal with this problem. This book contains the proceedings of the Symposium and faithfully records all discussions. The Symposium covered the present situation and future perspectives of IR techniques. International leaders in the field reviewed the results to date and the possible developments in telescope systems, detectors, cryogenics, filters, and interferometers. Individual con tributions were made by European and U. S. scientists in each of these fields.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La mesure des concentrations d'espèces à l'état de trace, susceptibles d'avoir un impact notable sur la santé, le climat ou la stabilité de la couche d'ozone constitue un véritable défi. Les prochaines missions spatiales, prévues à haute sensibilité, apporteront un progrès si et seulement si les paramètres spectraux nécessaires sont disponibles. Pour certaines espèces d'intérêt atmosphérique telles que le chlorure de nitryle (ClNO2), le phosgène (Cl2CO) et le nitrate de chlore (ClONO2), les données spectroscopiques sont incomplètes ou quasiment inexistantes. Le défi dans cette thèse consiste à obtenir des paramètres spectroscopiques (positions et intensités de raies ou sections efficaces d'absorption) pour ces espèces, en vue des applications atmosphériques. Cependant, hormis Cl2CO, la spectroscopie de ClNO22 et ClONO2 est rendue difficile par leur synthèse chimique très complexe, leur réactivité avec les métaux et les matériaux organiques et leur instabilité en présence de lumière et chaleur. De plus, ces molécules sont assez lourdes (présence du chlore avec ses deux isotopomères) et présentent des spectres denses et assez compliqués par de nombreuses perturbations qui affectent les niveaux de vibration-rotation.Dans le cas de ClNO2, des spectres ont été enregistrés dans la gamme 300 - 900 cm-1 avec de meilleures conditions expérimentales (haute résolution, basse température, long parcours, faible pression) en utilisant le rayonnement synchrotron de la ligne AILES à SOLEIL. Des modélisations précises des régions à 370 et 790 cm-1 ont été effectuées. Ces régions pourront être exploitées pour une future télédétection atmosphérique par spectroscopie IRTF respectivement par les instruments FORUM et IASI-NG. Les vibrations de basse énergie de ClONO2 jamais observées à haute résolution avant ce travail ont également été mesurées. Une première modélisation de la région de la torsion vers 120 cm-1 est présentée dans cette thèse. L'analyse de ces vibrations sera utile pour modéliser les bandes chaudes dans les fenêtres atmosphériques où ClONO2 est actuellement détecté, et in fine permettra d'aboutir à une restitution bien plus précise du profil de concentration de ClONO2. Concernant Cl2CO, des sections efficaces ont été mesurées au LISA, d'une part, à température ambiante pour clarifier les données des travaux antérieurs et, d'autre part, dans les conditions stratosphériques en soutien à la télédétection satellitaire.

Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Book excerpt: Molecular Spectroscopy: Modern Research explores the advances in several phases of research in molecular spectroscopy. This eight-chapter book commemorates the 25th anniversary of the annual Columbus Symposium on Molecular Structure and Spectroscopy, held in September, 1970. This book highlights the spectroscopic studies of molecular species in the gas phase and in matrices. Representative articles are also included that cover the applications of molecular studies in a wide variety of areas such as biophysics, astrophysical problems, and energy transfer processes. Other chapters describe the progress achieved in the technology of high resolution spectroscopy and the techniques and terminology of Lamb-dip spectroscopy. A comprehensive bibliography is included for most of the subjects discussed and this text concludes with tables of standard data listing secondary wavelength standards, fundamental constants, atomic masses, and conversion factors of interest to spectroscopists. Spectroscopists, chemists, and researchers will find this work invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: Le travail que je présente est une étude prospective de spectroscopie moléculaire effectuée dans le domaine de l'infrarouge lointain (30-500 cm-1) jusqu’alors très peu étudié en spectroscopie par transformation de Fourier. La mise au point au laboratoire de plusieurs dispositifs expérimentaux a permis d’enregistrer les spectres d’espèces moléculaires (à l’état gazeux) d’intérêts atmosphérique et astrophysique. Les spectres d’absorption et d’émission à haute résolution de molécules légères (cis- trans-HONO, H2O, NH3) obtenus par ces dispositifs apportent de nombreuses informations spectroscopiques. Une partie du manuscrit est consacrée à la présentation de ces spectres ainsi qu' à l’analyse rotationnelle des espèces moléculaires responsables des structures observées. Par la suite, nous avons enregistré les spectres d'émission dans l'infrarouge lointain de six petites molécules Hydrocarbures Aromatiques Polycycliques (PAHs) ainsi que le spectre d'absorption à température ambiante du naphtalène. Ces spectres sont d'un grand intérêt pour les futurs projets astrophysiques. Finalement, une partie de mon travail a été consacrée à la caractérisation expérimentale de la ligne d’extraction du rayonnement synchrotron infrarouge et infrarouge lointain (SIRLOIN-2 au LURE) et à l'utilisation de ce nouveau continuum lumineux pour l'enregistrement de spectres d'absorption à haute résolution.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Molecular Spectroscopy, Volume 3 provides information pertinent to the fundamental aspects of inorganic molecules and complexes. This book covers a variety of topics, including infrared spectrum, polyatomic ions, infrared emissions, and Raman spectra. Organized into five parts encompassing 72 chapters, this volume begins with an overview of the infrared spectrum of pyridine. This text then examines the results from studies of the infrared and Raman spectra of N2O4 in the solid and liquid phases at low temperatures. Other chapters consider the infrared spectrum of a mixture of N2O3 and N2O4, which has been studied in the liquid phase from 2 to 25 μ and in the solid phase from 2 to 35 μ, both at low temperatures. The final chapter describes the instrument developed for the measurement of rotatory dispersion and discusses some of the results obtained in the study of the complexes. This book is a valuable resource for chemists.

Download or read book Infrared Spectroscopy of Minerals and Related Compounds written by Nikita V. Chukanov and published by Springer. This book was released on 2016-03-09 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the application of IR spectroscopy in mineralogical investigations, as well as modern trends in the IR spectroscopy of minerals. It includes the most important methodological aspects; characteristic IR bands of different chemical groups and coordination polyhedra; application of IR spectroscopy to the investigation of the crystal chemistry of amphiboles, phyllosilicates, tourmalines etc.; neutral molecules entrapped by microporous minerals; and analysis of hydrogen in nominally anhydrous minerals. About 1600 IR spectra (illustrations as well as a list of wavenumbers) of minerals and some related compounds are accompanied by detailed descriptions of the standard samples used. Each spectrum provides information about the occurrence, appearance, associated minerals, its empirical formula, and unit-cell parameters. The book also provides insights into sample preparation and/or spectrum registration methods. It includes IR spectra of 1020 minerals that were not covered in the book “Infrared spectra of mineral species: Extended library” published in 2014 and written by one of the authors. On average, each page provides information on two minerals/compounds. Subsections correspond to different classes of compounds (silicates, phosphates, arsenates, oxides etc.). About 290 new spectra have been obtained, and the remaining 1310 spectra are taken from most reliable literature sources (published over the last 60 years) and are redrawn in a unified style.
