摘要
The localized Hartree-Fock and the open-shell LHF (OSLHF) approaches are reviewed and rederived under a unique formalism. Three different treatments of the OSLHF correction term are discussed and results for excitation energies are presented for small- and medium-size closed- and open-shell molecules.
