This model combines a modified Thole-type water model with distributed point polarizable, denoted DPP, with quantum Drude oscillators for treating polarization and dispersion interactions between the excess electron and the water molecules. It is demonstrated by examining several small water clusters that this model closely reproduces the relative energies of different isomers of the anions as well as the electron binding energies from ab initio MP2 calculations. The Drude/DPP model is used to carry out parallel tempering Monte Carlo simulations of (H2O)6-.} }
