Add to ORKGEPSC-DPS2011-775A new reactor has been designed for experimental simulation of Titan's atmospheric photochemistry and installed at SOLEIL Synchrotron Radiation Facility whose DISCO continuous-spectrum UV beamline is used as the energy source. The products of the photochemistry are detected in situ by mass spectrometry and ex situ by the GC-MS analysis of a cryogenic trap experiment. The formation of C2H2, HCN, C2H4, C2H6, CH3CN and C2N2 is observed and confronted with results of other Titan's photochemical simulation experiments
