Re: CCL:Origin of dipole moment in Gaussian



Dear Hans Martin,
 according to the manuals, output controlled by the POP
 keyword, including dipole and multipole moments, is expressed
 in the coordinate system defined by the 'standard
 orientation'. The origin of this system is the center of
 nuclear charge (presumably because this simplifies the
 evaluation of multipole terms). The orientation of the
 coordinate axes is determined by the molecular symmetry
 elements, if present.
