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.
