Abstract.
A partition of the atomic polar tensor (APT) into charge, charge flux,
and atomic and homopolar dipole fluxes is proposed by analyzing the variations
of the dipole moment vector with respect to the expectation integrals of
the atomic basis functions. The contributions in the expression obtained
for the dipole moment are invariant with respect to the origin of the system
and contain the atomic and homopolar dipoles as named before by Mulliken
and Coulson. Results for water molecule are presented as an illustration
of the method.
