    International audienceWe are designing and realizing an instrument for the spectroscopy of the volatile metabolome of the soil microorganisms. The use of optical telecommunication elements makes it possible to realize a compact source with a wide range of accessible frequencies (100 GHz-1 THz range; 3-33 cm⁻ ¹) with an accuracy of 10⁵ Hz (3.10⁻⁶ cm⁻¹), as well as a low bandwidth detection system. The instrument will discriminate among complex polar molecules. We report on the preliminary performances of parts of the source system
