Preliminary studies were carried out for the O+(4S 3/2) + methane reaction, which serves as a benchmark for developing the theory of polymer erosion by O+ under low Earth orbit conditions. Ab initio electronic structure calculations show that the interaction of O + with CH4 can lead to a large number of reaction products such as charge transfer, hydride abstraction, and H elimination. Based on the information obtained from these quantum chemistry calculations, a direct dynamics classical trajectory simulation was carried out at 5-eV relative translation energy and the chemical reaction channels predicted by the ab initio calculations are confirmed.
