 Hi --
 I was wondering if 1) Gaussian can calculate the exchange energy and 2) if
 there's a way to specify which spin electron you want to add?  Also, 3) is
 there a way to apply a magnetic field to a molecule?
 As far as I know, if you want to add a charge onto a molecule, you just
 write before the molecule specification:
 -1 2
 where the -1 is the charge and the 2 is the multiplicity.
 Thanks in advance...
