摘要
A comparison is presented of uncontracted multireference singles and doubles configuration interaction (MRCI) and internally contracted MRCI potential energy surfaces for the reaction H(S-2) + O-2 ((3)Sigma(-)(g)) -> HO2((2)A ''). It is found that internal contraction leads to significant differences in the reaction kinetics relative to the uncontracted calculations.
