According to a study from the United States, "The EUV photochemistry of methane is one of the dominant chemical processes in the upper atmospheres of Titan and Jovian planets. The dilution of CH4 with N-2 significantly changes the subsequent hydrocarbon chemistry initiated by EUV photoionization."

"At wavelengths below 80 rim, the presence of the dominant N-2 species in a N-2/CH4 gas mixture (=95/5) selectively enhances the formation of unsaturated hydrocarbons, such as benzene and toluene, while pure CH4 gas leads to a wide mixture of saturated/unsaturated ...
