Laser optoacoustic determination of atmospheric pollutants and their computer identification

The mathematical self-modeling method has been used to identify the samples of urban air from their IR spectra. The spectra of methane, carbon dioxide, carbon oxide, acetylene, and ethylene have been isolated from the spectra of samples. The data obtained have enabled us to investigate the ethylene content in the ambient atmosphere as a function of daytime using laser optoacoustic analysis.
