In a recent study1 of Li H2On (n 1–6) ionic clusters, we examined the performance of a
variety of one-particle and n-particle basis sets in predicting the structures and incremental
binding energies involving the smallest of the socalled hard ie, nonpolarizable cations.
Alkali cation-and alkaline earth dication-water clusters have been the subject of numerous
experimental studies2–5 due to the importance of ion–water interactions in a multitude of
chemical and biochemical phenomena. The primary goal of the Li H2On study was the …
