The Effective Fragment Potential (EFP) method in the General Atomic and Molecular Electronic Structure System (GAMESS) software suite has been used to study a wide variety of solvation studies for several years. Until recently, the EFP method has been restricted to closed-shell molecules. The electrostatics, exchange-repulsion, polarization and dispersion energy interaction terms of the EFP method are investigated and re-derived to study open shell molecules. These derivations have been coded into GAMESS and a variety of test cases are used to test the new additions to the code.
