Abstract
The absorption spectra of air pollutant gases have a complicated structure due to vibrational and rotational levels of the polyatomic molecules. The Fourier transform of the absorption spectra from a gas mixture shows the characteristic peaks for each component gas. The error due to wavelength jitter of the scanning laser is effectively reduced by a Fourier-transformed least-squares method. This process is applied to air pollution measurement.
