Thanks to a dedicated heterodyne detection by use of a new kind of molecular laser as local oscillator along with a Fast Fourier Transform Spectrometer, several pure rotation absorption lines of H 2 S and CH 3 OH around 1.073 THz have been recorded. %G English %L hal-03089129 %U https://cnrs.hal.science/hal-03089129 %~ CNRS %~ UNIV-LITTORAL %~ UNIV-VALENCIENNES %~ IEMN %~ JYB-LAB %~ UNIV-PARIS-SACLAY %~ UNIV-LILLE %~ TEST-HALCNRS %~ GS-CHIMIE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ LPCA
