Description:
The nature of information that can be retrieved from spectra obtained with Fourier transform spectroscopy is discussed. Nonlinear, least-squares analysis of spectra is capable of retrieving information that is beyond the reach of conventional methods and has improved precision and accuracy. These studies have allowed the approval of experimental design to the analysis of spectra to be placed on a quantitative basis. Fourier transform infrared spectroscopy was used to study quantitatively the kinetics and mechanisms of several chemical reactions that are of interest to atmospheric chemists and are important in the development of air pollution control strategies. The systems studied include the metastable, reactive, gaseous species, peroxynitric acid, hypochlorous acid, and dimethylnitrosamine. Rate constants related to the formation and decay of these species and infrared extinction data necessary for the quantitative analyses of these compounds were determined.
