Abstract
|
|
|
Fourier transform infrared spectroscopy(FTIR) is now a well established technique and its use will soon be routine in science field, especially a study of air pollution needing coverage of the infrared region from 5cm^(-1) to 4000cm^(-1). Recent developments in modulation techniques, in detectors and in computing systems have produced improved sign-to-noise-ratios, decreased observation times, and new applications such as time-resolved spectrometry of fast chemical reactions.
There have been significant advances in the use of scanning interferometers for the measurement of infrared spectra. It is the purpose of this article to outline the basis of principle of F.T.I.R and its application to detect not only trace amounts of air pollutants such as O_(3),SO_(2)---, also deducing a elementary reaction mechanism and kinetic parameters of reaction of O_(3)+SO_(2).
