Journal ArticleDOI
A long-path infra-red study of Los Angeles smog
TL;DR: In this article, a Fourier transform spectrometer operated at 0.25 cm−1 resolution was used in conjunction with a 1260m optical path folded along a base path of 23 m.
Journal ArticleDOI
A kilometer pathlength fourier-transform infrared system for the study of trace pollutants in ambient and synthetic atmospheres
Ernesto C. Tuazon,Richard A. Graham,Arthur M. Winer,R.R Easton,J. N. Jun. Pitts,Philip L. Hanst +5 more
TL;DR: A Fourier-transform infrared system operable at pathlengths up to 2 km has been constructed for the detection and measurement of trace contaminants in the ambient atmosphere and in controlled smog formation studies.
Journal ArticleDOI
Detection of Atmospheric Pollutants at Parts-per-Billion Levels by Infrared Spectroscopy
Philip L. Hanst,Allen S. Lefohn +1 more
TL;DR: In this article, the authors used the scanning Michelson interferometer, cooled solid state detectors, the fast minicomputer, and the multiple pass long path cell for infrared detection of air pollutants.
Journal ArticleDOI
Air pollution measurement by Fourier transform spectroscopy
TL;DR: The use of infrared methods in pollution measurement has been hampered by sensitivity limitations and by interferences from water vapor, but Fourier transform spectrometer systems reduce these limitations by their high optical efficiency and their ability to manipulate spectra for removal of interfering bands.
Journal ArticleDOI
Peroxychloroformyl nitrate: synthesis and thermal stability
TL;DR: Peroxychloroformyl nitrate, CIC(O)OONO 2, PCIFN has been identified as an oxidation product of chlorinated compound and as the principal product of the ultraviolet irradiation of Cl 2, NO 2, and CO mixtures in air as mentioned in this paper.
