Druck auf Anfrage Neuware - Printed after ordering - Collision-or interaction-induced spectroscopy refers to radiative transitions, which are forbidden in free atoms or molecules, but which occur in clusters of interacting atoms or molecules. The most common phenomena are induced absorption, in the infrared region, and induced light scattering, which involves inelastic scattering of visible laser light. The particle interactions giving rise to the necessary induced dipole moments and polarizabilities are modelled at long range by multipole expansions; at short range, electron overlap and exchange mechanisms come into play. Information on atomic and molecular interactions and dynamics in dense media on a picosecond timescale may be drawn from the spectra. Collision-induced absorption in the infrared was discovered at the University of Toronto in 1949 by Crawford, Welsh and Locke who studied liquid O and N. Through the 1950s and 1960s, 2 2 experimental elucidation of the phenomenon, particularly in gases, continued and theoretical underpinnings were established. In the late 1960s, the related phenomenon of collision-induced light scattering was first observed in compressed inert gases. In 1978, an 'Enrico Fermi' Summer School was held at Varenna, Italy, under the directorship of J. Van Kranendonk. The lectures, there, reviewed activity from the previous two decades, during which the approach to the subject had not changed greatly. In 1983, a highly successful NATO Advanced Research Workshop was held at Bonas, France, under the directorship of G. Birnbaum. An important outcome of that meeting was the demonstration of the maturity and sophistication of current experimental and theoretical techniques.

Descrizione articolo

Riassunto

This volume is a review of the latest progress in induced spectroscopy. It contains contributions from most major researchers in the fields of collision-induced light scattering and infrared absorption. It should be particularly valuable to spectroscopists who study dense fluids and solids. While aimed primarily at the specialist in spectroscopy, the book contains a number of review articles, with bibliographies, that are accessible to those knowing the fundamentals of infrared absorption and light scattering. These articles describe some novel applications of induced spectroscopy, such as the study of species trapped in fullerenes, and the modelling of stellar and planetary atmospheres. A decade of progress in induced spectroscopy is reviewed. Recent developments include deeper understanding of intermolecular induction mechanisms and their extension to ternary interactions; refined calculations of intermolecular potentials; more sophisticated structural and dynamical models of liquids and dense gases; and advanced lineshape theories that treat intercollisional interference and rotationally inelastic collisions. Emerging applications include induced spectra of van der Waals dimers and of species trapped in zeolites and fullerenes; and the modelling of stellar and planetary atmospheres.
