The PHAHST polarizable potentials, designed for material simulations, also utilize the induced dipole model. The complexity of solving for induced dipoles by SCF methods may be reduced by an empirical extrapolation scheme developed by Brooks et al. . An even simpler approach is afforded by the direct approximation of electronic polarization, where the atomic polarizabilities do not "feel" the fields generated by other induced dipoles, but only the fields generated by partial charges and the external field (if any); the approximation is thus E j ≈ E j,ext + E j,perm . This approach was utilized in the iAMOEBA polarizable water model, which successfully replicates many physical properties of water. However, the direct approximation has not yet been applied to a wider range of systems. In this work, we extended the usage of the fast direct approximation in various small organic molecules by deriving appropriate force field parameters in the context direct polarization.
