Abstract
Titan is the largest satellite of Saturn and the second largest satellite in the solar system. It is the only satellite in the solar system that has a dense atmosphere. Its atmosphere is dominated by N2 (98% by volume), with a small amount of CH4 (2% by volume) and tiny amounts of other organic molecules. Very recently, the Visual-Infrared Mapping Spectrometer (VIMS) on board the Cassini spacecraft detected in the atmosphere of Titan the 3.28 mm emission feature which is believed to arise from the C-H stretching mode of polycyclic aromatic hydrocarbon (PAH) molecules. PAHs are thought to be a major constituent of the Titan haze. How PAHs are formed in the Titan atmosphere is still a mystery. This paper discusses the observational properties, chemical structures, and formation mechanisms of PAHs in the atmosphere of Titan.
