Approaches to compute fractional contributions to the solvation free energy are developed in the context of continuum self consistent reaction field calculations (both classical and quantum mechanical), as well as in the framework of discrete molecular dynamics simulations. It is found that for a series of typical pharmacological drugs there is a good agreement between the different fractional descriptions. Algorithms reported here can be easily applied as molecular descriptors in the context of quantitative structure-activity relationships.
