WebAbout 2% of Titan’s atmosphere is methane, which undergoes photodissociation at the alpha-Lyman wavelength (121.6 nm). Methane fragments recombine into heavier organic molecules such as aliphatic and polycyclic aromatic hydrocarbons. The larger hydrocarbons condense into aerosols, particles suspended in air.
