We have no way to do this with Amber; not also that the OPLS-UA parameters
are very old ones. If you want to apply OPLS like parameters to arbitrary
molecules, code from either the Jorgensen group or from Schrodinger is
probably the best way to go.
The only "Amber" approach to general molecules is via antechamber and gaff2.
