    <skos:definition xml:lang="en">The FIRS-2 is a Fourier transform spectrometer operating in the far- (80-220 cm-1, recently extended to 340 cm-1) and mid-infrared (330-700 cm-1, recently extended to 1220 cm-1). Interferograms are mostly one sided, and the transformed spectra have an apodised resolution of 0.008 cm-1.</skos:definition>
