Long-path infrared spectroscopy has yielded data on the composition and chemistry of the polluted air at Pasadena, California. Infrared radiation was transmitted along a 417-meter path folded between mirrors in a glass tube 9 meters long. Spectra of polluted air were recorded with a Fourier transform spectrometer system and were plotted in ratio mode against the spectra of humidified reference air. This ratio plotting allowed the observation of weak pollutant absorption lines by removing the background spectrum of water and carbon dioxide lines. Data were taken in late November 1972 and in the summer of 1973. The chemistry of the air is discussed in terms of the observations.
