A RF capacitively coupled plasma in nitrogen methane mixture is used to simulate the production of aerosols observed in the atmosphere of Titan, satellite of Saturn. Plasma characteristics are studied by Optical Emission Spectroscopy. The gas temperature is deduced from the rotational spectra of the nitrogen second positive system. An evolution of the electron mean energy is also pointed out from the intensity evolution of this second positive system. A tentative of correlation between plasma spectroscopy and solid particles composition is done.
