Dear NWChem users and developers,
I would need to determine the effect of a point charge placed in a certain position on a molecule.
Is it possible to put a single electron in a given position? Do I need to set a static electric field to
stabilize it? Which is the correct directive to do that?

Thank you
Regards

Alessandro

Yeah!
Same question for me too...
In addition, I would like to see the effect of charged/uncharged atoms residing near 2 monomeric interaction partners.

thank you.

Applying such charges should work via the "bq" statement. See

As far as I know, you can also assign basis functions to these Bqs and monitor the resulting polarization effects.
