| Abstract: | The reaction between methyl radicals and carbon monoxide was studied by using the B3LYP/6-311G~(**)and QCISD(T)/6-311G~(**) single-point levels.The geometries for reacts,the transition states and the products were completely optimized.All the transition states were verified by the vibration analysis and the internals reaction coordinate(IRC) calculations.The results showed that the carbon monoxide can stabilize methyl radicals.This work will provide the theoretical foundation for flames of hydrocarbon fuel and protecting the atmosphere. |
