Download or read book Radical Ionic Systems written by Anders Lund and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now more than 20 years since the book "Radical Ions" edited by Kaiser and Kevan appeared. It contained aspects regarding generation, identification, spin density determination and reactivity of charged molecules with an odd number of electrons. New classes of reactive ion radicals have been detected and characterised since then, most notably cation radicals of saturated organic compounds. Trapping of electrons has been found to occur not only in frozen glasses but also in organic crystals. The structure and reactions of anion radicals of saturated compounds have been clarified during the last 20 years. We have asked leading experts in the field to write separate chapters about cation radicals, anion radicals and trapped electrons as well as more complex systems of biological or technological interest. More attention is paid to recent studies of the ions of saturated compounds than to the older and previously reviewed work on aromatic ions. In the case of trapped electrons full coverage is out of the question, and focus is on recent efforts to characterise the solvation structure in ordered and disordered systems.

Available in PDF, EPUB and Kindle. Book excerpt: The Tunable Lasers and Applications Conference was held in Loen, Norway, on June 6-11, 1976. This conference dealt with the technology of tunable lasers from the vacuum ultraviolet to the far infrared and their application in the areas of photochemistry, chemical kinetics, isotope separation, at mospheric photochemistry and environmental studies, photobiology, and spec troscopy. The need for such a conference grew out of the rapidly expanding use of tunable lasers in a broad range of disciplines. The conference was attended by 130 scientists representing Japan, Italy, West Germany, Canada, Israel, France, England, Norway, Sweden, Brazil, Den mark, Finland, the Netherlands, the Soviet Union, and the United States. The location of the conference in Loen, Nordfjord, was chosen because of the magnificent beauty of its aqua-blue fjords surrounded by glacier-capped mountains and lush green hillsides. The Alexandra Hotel was a perfect host for such a conference with first class services, superb smorgesbord, and ex cellent audio-visual facilities. The atmosphere was free of distractions and provided for a relaxed interchange of ideas. An afternoon hike was arranged to the Briksdal glacier while the highlight of the outdoor activities was a bus-ship excursion to the magestically splendid Geiranger fjord. A sumptuous banquet was followed by an interesting'and entertaining illustrated talk on high-speed and underwater photography by Professor Harold Edgerton from MIT. Financial support from our sponsors is gratefully acknowledged in help ing to make this conference a complete success.

Available in PDF, EPUB and Kindle. Book excerpt: For many years, the related fields of molten salts and ionic liquids have drifted apart, to their mutual detriment. Both molten salts and ionic liquids are liquid salts containing only ions - all that is different is the temperature! Both fields involve the study of Coulombic fluids for academic and industrial purposes; both employ the same principles; both require skilled practitioners; both speak the same language; all then that is truly different is their semantics, and how superficial is that? The editors of this book, recognising that there was so much knowledge, both empirical and theoretical, which can be passed from the molten salt community to the ionic liquid community, and vice versa, organised a landmark meeting in Tunisia, designed to bridge the gap and heal the rift. Leaders from both communities met for a week for a mutual exchange, with a high tutorial content intermixed with cutting edge findings. This volume is a condensate of the principal offerings of that week, and emphasises the success which was achieved. Indeed, four future biannual meetings, under the title of “EUCHEM Conferences on Molten Salts and Ionic Liquids”, have now been planned as a direct result of this meeting of minds. Topics discussed in this volume include structure, dynamics, electrochemistry, interfacial and thermodynamic properties, spectroscopy, synthesis, and theoretical studies. Experimental and theoretical methods for investigating these data are elaborated, as are techniques for data collection and analysis. This book represents the first serious discussion on the transfer of these methods and techniques between the differing temperature regimes, and is a major contribution to the future of both fields.

Download or read book Gas Lasers written by E. W. McDaniel and published by Academic Press. This book was released on 2013-10-22 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Atomic Collision Physics, Volume 3: Gas Lasers describes the applications of atomic collision physics in the development of many types of gas lasers. Topics covered range from negative ion formation in gas lasers to high-pressure ion kinetics and relaxation of molecules exchanging vibrational energy. Ion-ion recombination in high-pressure plasmas is also discussed, along with electron-ion recombination in gas lasers and collision processes in chemical lasers. Comprised of 14 chapters, this volume begins with a historical summary of gas laser developments and an overview of the basic operating principles of major gas laser types. The discussion then turns to the mechanism of formation of negative ions in gas lasers; ion-ion recombination in high-pressure plasmas; electron-ion recombination in gas lasers; and collision processes in chemical lasers. Subsequent chapters focus on high-energy carbon dioxide laser amplifiers; spectroscopy and excited state chemistry of excimer lasers; rare-gas halide lasers; transient optical absorption in the ultraviolet; and pre-ionized self-sustained laser discharges. The final chapter considers the stability of excimer laser discharges. This book will be of interest to physicists and chemists.

This book was released on 2013-06-29 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 Antwerp Advanced Study Institute on "Physics of Polarons and Excitons in Polar Semiconductors and Ionic Crystals" took place from July 26 till August 5 at the Conference Center Priorij Corsen donk, a restored monastery, close to the city of Antwerp. It was the seventh Institute in our series which started in 1971. This Advanced Study Institute, which was held fifty years after Landau introduced the polaron concept, can be considered as the third major international symposium devoted to the physics of pola rons. The first such symposium took place in St. Andrews in 1962 under the title "Polarons and Excitons" [I]. The early theoretical developments related to polarons were reviewed in depth at this meeting; the derivation of the polaron hamiltonian by Frohlich, the Frohlich weak coupling theory (and the equivalent weak coupling canonical transformations), the Landau-Pekar and Bogolubov strong coupling theory and the Feynman polaron model formulated with his path integrals. The main emphasis was on the polaron self-energy, effective mass and mobility. From the experimental side the first evidence for polaron effects was provided by the pioneering cyclotron and mobility measurements o~ the silver halides by F. e. Brown and his group. Also the significance of polaron effects for the under standing of excitons in ionic crystals was a central topic in St. Andrews. The second Advanced Study Institute concerning polaron physics was organized at the University of Antwerp (R. U. C. A.
