This interdisciplinary volume is an excellent resource for anyone who wants an in-depth understanding of current and emerging trends in gaseous measurement techniques. It provides both qualitative and quantitative introductions to the physics involved in using remote observations to collect data and offers numerous examples that encourage new applications of existing technologies. Compiled by an authority on spectroscopy, chemical kinetics and infrared emissions from combustible sources, this volume compares burn-off flare and stack plume emission spectra with parametric calculations performed with equally high spectral resolution ... discusses sensitivity of spectra to source temperature, and behavior of emission and ab­ sorption linewidths with temperature ... reviews the emission-absorption techniques for determining temperature and species concentration profiles ... and much more. Infrared Methods for Gaseous Measurements is a vital research tool for photo-optical instrumentation engineers; electro-optical engineers; chemical, aerospace, automotive, combustion, environmental, and mechanical engineers; and technologists involved in radiation, infrared or laser research. The book also serves as an excellent resource for graduate molecular spectroscopy courses and postgraduate infrared technology seminars.
