Available in PDF, EPUB and Kindle. Book excerpt: In this book, renowned scientists describe the various techniques used to detect and characterize extrasolar planets, or exoplanets, with a view to unveiling the “tricks of the trade” of planet detection to a wider community. The radial velocity method, transit method, microlensing method, and direct imaging method are all clearly explained, drawing attention to their advantages and limitations and highlighting the complementary roles that they can play in improving the characterization of exoplanets’ physical and orbital properties. By probing the planetary frequency at different distances and in different conditions, these techniques are helping astrophysicists to reconstruct the scenarios of planetary formation and to give robust scientific answers to questions regarding the frequency of potentially habitable worlds. Twenty years have passed since the discovery of a Jupiter-mass companion to a main sequence star other than the Sun, heralding the birth of extrasolar planetary research; this book fully conveys the exciting progress that has been achieved during the intervening period.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in English in 1973. This volume traces the development of the revolution which so drastically altered man’s view of the universe in the sixteenth and seventeenth centuries. The "astronomical revolution" was accomplished in three stages, each linked with the work of one man. With Copernicus, the sun became the centre of the universe. With Kepler, celestial dynamics replaced the kinematics of circles and spheres used by Copernicus. With Borelli the unification of celestial and terrestrial physics was completed by abandonment of the circle in favour the straight line to infinity.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of laser-based sources of ultrafast infrared pulses has extended the study of very fast molecular dynamics to the observation of processes manifested through their effects on the vibrations of molecules. In addition, non-linear infrared spectroscopic techniques make it possible to examine intra- and intermolecular interactions and how su

Download or read book Infrared Spectroscopy of Diatomics for Space Observation written by Pierre-Richard Dahoo and published by John Wiley & Sons. This book was released on 2018-01-03 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes different theoretical models developed to identify the near and mid infrared (IR) spectra of diatomic molecules isolated in the gas phase or subjected to environmental constraints, useful for the study of environmental sciences, planetology and astrophysics. The applications presented show how molecular interactions modify the near and mid IR spectra of isolated diatomics under the effect of pressure, a nano-cage (substitution site, Clathrate, Fullerene, Zeolite) or surfaces, to identify the characteristics of the perturbing environment.

Download or read book Spectroscopy of the earth s Atmosphere and interstellar Medium written by K.N. Rao and published by Academic Press. This book was released on 2012-12-02 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectroscopy of the Earth's Atmosphere and Interstellar Medium focuses on the characteristics of the electromagnetic spectrum of the Earth's atmosphere in the far-infrared and microwave regions. It discusses the modes of observation in field measurements and reviews the two techniques used in the spectral region. Organized into six chapters, this volume begins with an overview of the effect of water-vapor absorption, followed by a discussion on the two frequently used method for deriving atmospheric parameters from high-resolution infrared atmospheric spectra, namely, the equivalent width (EW) technique and the nonlinear least-square fitting (NLSF). Other chapters consider the mechanisms by which interstellar clouds are formed. In addition, the book explores the composition of interstellar clouds, ion-molecule reactions, and the formation of stars. This book will be useful to anyone involved in, or interested in learning more about the field of atmospheric spectroscopy, including scientists, aeronomers, astronomers, astrophysicists, and students.

Download or read book Infrared Spectroscopy of Triatomics for Space Observation written by Pierre-Richard Dahoo and published by John Wiley & Sons. This book was released on 2019-01-03 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the application of the different theoretical models described in Volume 1 to identify the near-, mid- and far-infrared spectra of linear and nonlinear triatomic molecules in gaseous phase or subjected to environmental constraints, useful for the study of environmental sciences, planetology and astrophysics. The Van Vleck contact transformation method, described in Volume 1, is applied in the calculation and analysis of IR transitions between vibration–rotation energy levels. The extended Lakhlifi–Dahoo substitution model is used in the framework of Liouville’s formalism and the line profiles of triatomic molecules and their isotopologues subjected to environmental constraints are calculated by applying the cumulant expansion. The applications presented in this book show how interactions at the molecular level modify the infrared spectra of triatomics trapped in a nano-cage (substitution site of a rare gas matrix, clathrate, fullerene, zeolite) or adsorbed on a surface, and how these interactions may be used to identify the characteristics of the perturbing environment.

This book was released on 2019-02-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage est dédié à l’application des différents modèles théoriques pour identifier les spectres IR proche, moyen et lointain de molécules triatomiques, linéaires ou non linéaires, en phase gazeuse ou soumises à des contraintes environnementales, utiles aux sciences de l’environnement, la planétologie et l’astrophysique. La méthode de transformation de contact de Van Vleck est appliquée dans le calcul et l’analyse des transitions IR entre les niveaux d’énergie de vibration-rotation. Le modèle de substitution étendu de Lakhlifi-Dahoo est utilisé dans le cadre du formalisme de Liouville et les profils de raies de molécules triatomiques et leurs isotopologues soumis à des contraintes environnementales sont calculés en appliquant le théorème des cumulants. Les applications montrent comment les interactions à l’échelle moléculaire modifient les spectres IR d’une triatomique piégée dans une nano-cage (site de substitution d’une matrice de gaz rare, clathrate, fullerène, zéolithe) ou adsorbée sur une surface et permettent d’identifier les caractéristiques de l’environnement perturbateur.

Download or read book The Infra red Spectra of Complex Molecules written by L. Bellamy and published by Springer. This book was released on 1975-06-26 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The full revision of this text has presented a number of problems. The basic data have changed little since the second edition, although they have been much extended in depth and in detail. To some extent this has helped to shorten the present text as many controversial issues which needed to be presented at some length have now been resolved so that only the final conclusions need to be given. However, it remains the case that very few new group frequencies have emerged over the past fifteen years and the emphasis of group-frequency studies has tended to shift away from the identification of specific groups towards their other possible uses in the solution of structural and chemical problems. The study of the interplay of mechanical and electronic effects in determining the directions and extents of group-frequency shifts which result from changes in the substituents has told us much about chemical mechanisms themselves, and has opened up new possibilities for the use of group frequencies in areas such as the study of rotational isomerism, the measurement of bond angles, and the use of frequency relationships to derive other chemical and physical properties.
