β¦ Synopsis
Numerical analysis revealed that the closed-shell complex molecular-orbital (CMO) wavefunctron.
which describesa signifrcant part of the electron correlation in molecules, may be transformed mto a very simple pairing form. This feature of the CM0 method IS essential for developmg an efficient complex configuration mixing scheme, analogous to the oonfiitionmteractlon method It should allow a rehable descripuon of electron correlation in systems beyond the reach of present-day theories.
