Chemical characterization of aerosol particles by Raman spectroscopy

Microparticles play a very important role in areas of atmospheric chemistry, combustion, interfacial science and others. Of particular importance is a knowledge of the chemical composition of these airborne particles. Until recently, much of the chemical information could only be obtained by analyzing sufficient quantities of particles collected on some substrate surfaces. In this paper, some of our work on chemical characterization of single particles by Raman spectroscopy is described. 7 refs., 6 figs., 2 tabs.
