   Dear Dave,

   I would also agree charges should be standardly HF/6-31G*
   level, due to polarity of the charge distribution, etc.
   As far as the terminology, however, I think I have never
   seen a reversal of the standard QM notation in the literature.
   Looks more complicated than it was at the beginning.....

   Best wishes, Jiri
