This leads to charge separations in molecules that are exaggerated. In a modified Mulliken population analysis, this problem can be reduced by dividing the overlap populations between the corresponding orbital populations and in the ratio between the latter. This choice, although still arbitrary, relates the partitioning in some way to the electronegativity difference bet… gratis suchbilder
