Elsevier Collisional Effects on Molecular Spectra: Laboratory Experiments and Models, Consequences for Applications

Collisional Effects on Molecular Spectra: Laboratory Experiments and Models, Consequences for Applications, Second Edition provides an updated review of current experimental techniques, theoretical knowledge and practical applications. After an introduction to collisional effects in molecular spectra, the book takes a threefold approach where it highlights key models, reviews available data, and discusses the consequences for applications. Areas covered include heat transfer, remote sensing, optical sounding, metrology, probing of gas media and climate predictions. An extensive bibliography and discussion of remaining problems and future directions complete the text. Gas phase molecular spectroscopy is a powerful tool for obtaining information on the geometry and internal structure of isolated molecules and the interactions that they undergo. It facilitates measurement, modeling and prediction of the influence of pressure (i.e.. of intermolecular collisions) on the spectra of gas molecules which must be taken into account for the correct analysis and prediction of the resulting spectra. In recent years, there have been considerable improvements in the field to meet the ever-increasing demand for accuracy and scope of applications. Drawing on the extensive experience of its expert authors, this book presents a valuable guide for all those involved with sourcing, researching, interpreting or applying gas phase molecular spectroscopy techniques across a range of fields. Provides updated information on the latest developments in measuring, modeling and predicting the influence of pressure on the spectra of gas molecules, including isolated line shapes, line-broadening and -shifting, line-mixing, the far wings and associated continua, and collision-induced absorption Reviews recently developed experimental techniques of high accuracy and sensitivity Highlights the latest practical applications in areas such as metrology, probing of gas media and climate prediction
