Formation of products in a glow discharge in the medium of argon with small additives (0.2-0.8 mole %) of methane and cyclohexane both with and without oxygen additives (up to 2 mole %) at a pressure of 10-1 Torr has been studied by the method of matrix IR-spectroscopy. A number of stable and labile electrically neutral intermediates have been fixed in the formed products, which allowed conclusions on methane and cyclohexane reactions proceeding in cold plasma at a low pressure. In particular, methane decay reversibility in cold plasma conditions and cyclohexane tendency to cycle decay are shown; evidences of the nonradical mechanism of formation of lower alkenes and olefin from cyclohexane in these conditions are obtained.
