Abstract:
The design and specifications of experimental set-up, consisting of Fourier-spectrometer IFS-125 HR and 30-meter base length multipass cell with a White optical system, are described. The optical path length of more than 600 meters is obtained. The results of the measurements of atmospheric air spectra with a spectral resolution of 2Ч10-2 сm-1 and a sensitivity of less than 10-8 сm-1 are presented. It is shown that very weak absorption spectra of atmospheric molecules including their isotopic modifications could be detected certainly.
