| Abstract | A new quantum chemically based approach to calculate the octanol/water partition coefficient in its logarithmic form (log K-OW) is presented. Semiempirically estimated enthalpies or free energies of solvation can be used to model the polar (electrostatic) interaction contribution to log K-OW, and the molecule's contact surface area to water may be taken proportional to the nonpolar interaction portion (van der Waals and cavitation energy). First results based on a simple bilinear regression model are discussed and compared with group contribution methods for a set of 12 aromatic phosphorothionates. |
