TL;DR: In this paper, a 20 pass, 10 m cell was used, and IR spectra in the 8 to 12 μ region of 70 ppm by weight of Freon-12 and 10 ppm of methanol were obtained.
Abstract: Bar-Lev (1967) described an instrument incorporating a dual detector, dual beam Michelson interferometer, and presented experimental results on the detection of gases in air. A 20 pass, 10 m cell was used, and IR spectra in the 8 to 12 μ region of 70 ppm by weight of Freon-12 and 10 ppm by weight of methanol were obtained. Single 1 s scans were used and emphasis was apparently placed on speed. It seemed to us that such instrumentation should be capable of detecting gas at concentrations lower than those reported, and we consequently carried out the measurements described below.

TL;DR: In this article, the advantages and disadvantages of apodization in submillimetre Fourier transform spectroscopy were discussed in terms of experimental results obtained observing emission of the stratosphere from an aircraft.
8 citations
TL;DR: In this paper, the 13C satellites in the proton spectrum as well as the undecoupled 13C resonance spectrum of β-1,2,3,4,5,6-hexachlorocyclohexane were observed by the Fourier transform sensitivity enhancement technique.

TL;DR: In this paper, an optical Fourier synthesis method was applied to the reconstruction of spectra in Fourier spectroscopy, where a Michelson interferometer was used for generating the harmonics.
