Atmospheric pollutants, Raman spectroscopy

A detailed understanding of our atmosphere, and of the various photochemical or collisional processes which determine the atmospheric composition, is of fundamental importance for mankind. Since in densely populated industrial areas air pollution has become a serious problem, the study of pollutants and their reactions with natural components in the atmosphere has become an urgent demand. Various techniques of laser spectroscopy can be successfully used in atmospheric and environmental research direct absorption measurements, laser-induced fluorescence, spontaneous Raman scattering, or coherent anti-Stokes Raman spectroscopy (CARS see Chap.9) can be utilized either for in situ measurements or for remote sensing.
