Notes:
A new definition of the MO-LCAO effective atomic charge is proposed, based on the concept of the topo-logical atom A general equation for the MO-LCAO electron occupancy of a topological atom is derived. It is shown that the intuitively introduced Mulliken gross atomic population is in fact an approximation to the electron occupancy of the corresponding topological atom. An approximate semiempirical procedure for evaluating the effective charge and effective radius of the topological atom is discussed.
