自由基CS与O2最佳反应通道的理论研究
Theoretical Study on the Best Reaction Channel of the CS Radical with O2 Molecule
【摘要】 应用量子化学从头算和密度泛函理论(DFT),对CS自由基与O2分子反应的单、三重态势能面进行了研究.在UB3LYP/6-311G(d,p)水平上优化了反应通道上各驻点的几何构型.在CCSD(T)/6-311G(d,p)水平上计算了各物种的单点能,并对总能量进行了零点能校正.研究结果表明:主要反应通道在三重态势能面中.主要产物是P3(OCS+3O),次要产物是P1(CO+SO).
【Abstract】 Using the ab initio calculation and density function theory(DFT),the singlet and triplet potential energy surface(PES) of the CS+O2 reaction were studied.The geometries of all species were optimized at the UB3LYP/6-311G(d,p) level and all the energies of the species were obtained with the correction of ZPVE at the CCSD(T)/6-311G(d,p) level.The calculated results indicate that all the major pathways of the reaction are obtained on the triplet potential energy surface.The main product of the reaction is P3(OCS+3O),the inferior product is P1(CO+SO).
