Comparison of Models With Distributed Polarizable Sites For Describing Water Clusters

In this work we examine three water models, including one developed by us, with distributed polarizable sites. These models are assessed by comparison with the results of MP2 calculations. The use of distributed polarizable sites is found to be especially important for describing the 3-body interaction energies of water clusters. It is also shown that all-atom repulsion terms are necessary to accurately describe cluster geometries
