Fourier Transform Infrared Spectroscopy: Demonstration of Measurement Capabilities in the Laboratory and the Field.

Abstract

The measurement capabilities of an infrared interferometer spectrometer are documented for both field and laboratory usage. This instrument provided intermediate resolution coverage (0.3/cm to 5/cm) in the 1.6 to 5.4 micron spectral interval. It has been used in the field to study radiation from aircraft exhaust plumes, background emission, and atmospheric transmission. In the laboratory, line spectra of flames have been measured and nonequilibrium vibrational temperatures derived. System configuration, operating procedure, and data processing are discussed. The performance of the interferometer is illustrated by typical spectral data. (Author)
