Charge distribution analysis in terms of Berlin's binding and antibinding regions for Li₂ and F₂

The MCSCF wave functions of Das for Li 2 , and Das and Wahl for F 2 , have been analyzed in terms of Berlin's binding and antibinding regions. The effect of electronic correlation on the charge distributions in these regions is studied. The process of bond formation in going from separated atoms to the correlated molecule is also discussed with reference to Berlin's regions.
