The Effective Fragment Potential (EFP), a general method for describing intermolecular interactions, including liquid behavior and the mixing of liquids, has been implemented into the GAMESS computational chemistry package. Following a brief introduction to the EFP method, the application of EFP combined with Monte Carlo Simulated Annealing (MC/SA) to the mixing of water and several alcohols with increasing alkyl chain lengths will be presented. The EFP calculations are followed by single point energy calculations at fully quantum levels of theory. The predictions will be compared with available experimental data.
