Abstract

The Fourier Transform Spectrosetry can be remarkably simplified in the case of the detection of siall gaseous aolecules by taking advantage of the periodicity of the absorption spectrua. The instruient includes an interferometric device adjusted to a fixed optical path difference used as a signature of the molecule. High sensitivity and remarkable discrisination power are obtained.
