The FANTASIO+ set-up\footnoteDidriche et al. , Mol. Phys. 2010, \textbf108, 2158-2164 (for 'Fourier trANsform, Tunable, diode and quadrupole mAss spectrometers interfaced to a Supersonic expansIOn') was upgraded by implementing a pulsed nozzle and a liquid injector. Experiments were performed to test the new capacities of this improved set-up. The first results will be presented, among which the CW-cavity ring down spectra of the ¹²C₂H₂-H₂O and ¹²C₂H₂-D₂O absorption bands in the 2CH excitation range (1.5 µm). The first analyses of these spectra will be presented.
