This book was released on 1998 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le cadre du centre d'etudes et de recherches lasers et applications, deux equipes du laboratoire de spectroscopie hertzienne et du laboratoire de cinetique et chimie de la combustion ont decide de reunir leurs competences tant en spectroscopie qu'en cinetique pour developper un projet de recherche commun. Celui-ci a pour objet l'etude de radicaux, en particulier ceux qui peuvent intervenir dans les processus chimiques complexes du milieu atmospherique. Les informations obtenues en laboratoire permettront d'etablir des modeles utilises en chimie atmospherique. L'etude et le developpement d'un dispositif de photolyse laser uv/ detection resolue dans le temps dans le domaine des frequences (sub)millimetriques ont ete realises dans le cadre de ce travail. La mise au point de ce systeme a ete realisee par l'etude du radical so produit par photolyse laser de cl#2so a 193 nm. Les spectres de rotation pure de l'etat electronique fondamental et des deux premiers etats excites ont ete mesures jusque 936 ghz, dans des etats vibrationnellement excites jusque v=17. Les resultats d'une etude portant sur un radical d'interet atmospherique, ch#3o, produit par photolyse laser de ch#3ono, sont presentes. Deux types d'experiences ont ete entreprises : une etude spectroscopique dans le domaine submillimetrique et une etude cinetique, avec suivi du radical par fluorescence induite par laser. La reaction avec no a ete etudiee a temperature ambiante dans la gamme de pression 14-510 torr et a quelques pressions dans la gamme de temperature 13-91 c.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Spectroscopic Monitoring of the Atmosphere provides a comprehensive overview of cutting-edge technologies and monitoring applications. Concepts are illustrated by numerous examples with information on spectroscopic techniques and applications widely distributed throughout the text. This information is important for researchers to gain an overview of recent developments in the field and make informed selections among the most suitable techniques. This volume also provides information that will allow researchers to explore implementing and developing new diagnostic tools or new approaches for trace gas and aerosol sensing themselves. Advances in Spectroscopic Monitoring of the Atmosphere covers advanced and newly emerging spectroscopic techniques for optical metrology of gases and particles in the atmosphere. This book will be a valuable reference for atmospheric scientists, including those whose focus is applying the methods to atmospheric studies, and those who develop instrumentation. It will also serve as a useful introduction to researchers entering the field and provide relevant examples to researchers and students developing and applying optical sensors for a variety of other scientific, technical, and industrial uses. - Overview of new applications including remote sensing by UAV, laser heterodyne radiometry, dual comb spectroscopy, and more - Features in-situ observations and measurements for real-world data - Includes content on leading edge optical sensors

Download or read book Physical Supramolecular Chemistry written by L. Echegoyen and published by Springer. This book was released on 2011-09-20 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of Supramolecular chemistry has reached a high level of sophistication and maturity, especially in the last 5-10 years. The sophistication is primarily evident in the highly complex chemical architectures that have been synthesized to accomplish specific functions such as selective binding and transport of substrates, in catalysis, and for the formation of assemblies, to name just a few of the applications. Many other molecular structures have been synthesized to form unusual materials with interesting and/or useful properties. From this point of view, the field is mature, as would have been anticipated from its historical development, starting in 1967 with Pedersen and the crown ethers. Since that time, the field has evolved mainly from a synthetic organic perspective. There are notable exceptions to this statement, but in general it holds true that the major advances were made in the laboratories of organic chemists with considerable topological insight. by The design and synthesis of the molecules was also partly guided physical insight provided by measurements and calculations done by physical chemists. As a consequence, many chemical systems were synthesized in relatively small amounts to afford their full characterization but not in large enough quantities to fully explore their intended properties or structures. Thus in the decades of the 70's and 80's physical chemists played an important role in guiding the future directions in the field, providing needed structural and energetic information and providing improved experimental designs.
