Apr 21, 2022 · Mulliken's interpretation of this result is that one electron in molecular orbital ψ t contributes c i j 2 to the electronic charge in atomic orbital φ j, c i k 2 to the electronic charge in atomic orbital φ k, and 2 c i j c i k S j k to the electronic charge in the overlap region between the two atomic orbitals.

The Mulliken analysis which turns the projection of the planewaves onto the pseudo-atomic orbitals, into quantified charges per atom, proceeds as described in Mulliken's work , , , . Essentially the charge per atom is obtained from the weighted total of the product of the density and overlap matrices and the interested reader is advised to consult the aforementioned …
