Michael,
	I have not experimented much with different basis sets, but the effect is
not much different using HF/6-31G* or MP2/6-31G*.  I had no luck at all
seeing any attraction between, for example, nitrobenzenae and toluene using
AM1 or PM3 and a   minimal basis set (3-21G).  I did not try CI, but I
agree that is would be a good idea.
	Ned
