Explanation of … WebApr 8, 2024 · Let us consider the following model of the detachment or attachment of an electron in an \(N\)-electron system. In this model, both the parent molecule and the species generated by adding or removing an electron are treated at the single-determinant level. The Hartree-Fock orbitals of the parent molecule are used to describe both species.
