Original Abstract

A qualitative FTIR analysis of products formed in an abnormal glow discharge was studied at atmospheric pressure and ambient temperature. The used nitrogen-methane mixtures (0.5 - 2 % of methane) was corresponded to the composition of Titan's atmosphere. Fourier Transform Infrared (FTIR) spectra were taken in dependence of discharge current and gas mixture composition. Simple hydrocarbons and nitriles such C2H2, C2H6, C2H4, C3H8, HCN, NH3, HC3N and CH3CN were identified as the main discharge products. CN and CHx radicals have been found to be the main initializers of organic chemistry in our discharge. Such a plasmachemistry may provide some insight into the chemical processes prevalent in the atmosphere of Titan
