Download or read book Methane Spectral Analysis written by G. Dresselhaus and published by . This book was released on 1980 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vibration-rotation hamiltonian for cubic symmetry molecules was developed using an expansion in terms of angular momentum matrices. A computer program for ground state of the methane molecule was written which gave symmetries and values for the rotational levels. A perturbation theory was developed for the excited vibrational states based on spherical jellium molecule for the ground state. This perturbation was shown to give good convergence for the nearly degenerate v2, v4 vibrational levels in methane. Preliminary work on the development of computer programs for a calculation of the vibrational levels of molecules using LCAO x(alpha) calculations for the electronic structure was carried out.

Available in PDF, EPUB and Kindle. Book excerpt: Nous avons mis en place un dispositif permettant l'acquisition d'échos de photons stimulés infrarouges à l'échelle femtoseconde. Le but est d'examiner la dynamique vibrationnelle aux temps courts de métaux carbonyles (W(CO)6 and Fe(CO)5) piégés en matrice cryogénique (4-50 K). Cet environnement solide, issu de la condensation d'un mélange gazeux contenant une impureté et un gaz inerte (N2, CH4, Ar, etc.), est propice à l'étude de systèmes dans leur état fondamental. L'excitation d'une vibration moléculaire s'atténue toujours temporellement, ce qui correspond dans le domaine spectral à un élargissement des raies d'absorption. L'étude de la dynamique vibrationnelle vise à examiner les causes physiques à l'origine de cet élargissement spectral. Typiquement, elles sont de trois sortes : phénomènes intramoléculaires, interactions entre molécules piégées et interactions entre la molécule piégée et l'environnement. Les échos de photons permettent de distinguer les contributions homogènes et inhomogènes de l'élargissement spectral et de caractériser les processus de déphasage, de relaxation des populations et de diffusion spectrale. Parmi les résultats obtenus, nous avons mis en évidence l'influence des phonons spécifiques aux matrices moléculaires (ex : libration de N2 et rotation de CH4 ) sur le déphasage vibrationnel ainsi que l'influence de la transition de phase du méthane solide à 20 K sur la dynamique vibrationnelle. Nous avons également montré que la dynamique vibrationnelle était dépendante du site cristallographique dans lequel est piégée la molécule. Enfin, en excitant plusieurs modes de vibration simultanément, nous avons pu examiner les couplages intramoléculaires.

Download or read book Methods of Detecting Exoplanets written by Valerio Bozza and published by Springer. This book was released on 2016-04-12 with total page 262 pages. 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.
