The emission of SO2 from coal-burning power plants, metal smelters, and other sources has a huge impact on the environment through the formation of acid rain. However, do SO2 emissions also contribute to global warming? SO2 is a bent molecule, and so all three of its vibrations, the symmetric and asymmetric stretches and bending, are IR active. The wavelength maximum of these three bands are 8.7, 7.3 and 19.3 um, respectively. Based on this information, is SO2 a trace greenhouse gas? If so, which specific vibrations would be responsible for its contribution to global warming?
