The free energies of partitioning between water and chloroform are predicted for six nucleic acid bases using the SM5.4/A water and chloroform solvation models. We obtain a mean unsigned accuracy of 0.2 log10 units compared to experiment. Predictions are made for an additional six unnatural nucleic acid bases. Functional group contributions to the solvent-solvent partitioning phenomenon are examined and the validity of fragment-based partitioning models is assessed
