Ab initio MO studies on the potential energy surface of the methyl chloride radical anion

The potential energy surface of the methyl chloride radical anion has been studied by ab initio molecular orbital theory. The following calculated results are obtained, different from the reported C-Cl dissociation potential curves: (1) A shallow least energy point (stationary point) is found within C 3υ symmetry in cases where dynamical correlation effects are taken into consideration
