Hey.

I'm just learning to use NWChem (wrt my BsC project), and need to run some calculations (HgBr2 geometry optimization and DFT energy) using Stuttgart ECPs. For spin-orbit ECPs I'm planning to use Stuttgart ECPs:

To qoute NWChem manual:

"For example, in the literature the Stuttgart potentials are defined as ?Ul and, hence, have to be multiplied by 2 / (2l + 1)."

Does that mean that I need to multiply each coefficient in manually specified ECP by 2 / (2l + 1)?
