In this paper, we report the results of Monte Carlo (MC) simulations of small N0<:Li+(H20), (1 5 n 5 28) clusters. We looked at the equilibrium structures of the clusters' hydration shells and the adiabatic potential energies of the clusters as functions of interionic distance and cluster size. From these simulations, we discovered the distributions of the water molecules around the ions can be separated into two cases depending on the interionic distance. The first describes the separated-ions case and the second characterizes the complexed ion pair. In addition to looking at the structure of the hydration shells of the clusters, we also examined their energetics. From the MC averaged energies, we obtained an effective adiabatic potential energy curve for each of the clusters. We found that the total potential energy decreases with increasing number of waters implying that the net interaction of the addition of the waters is attractive at all interionic distances. We also noted that the potential energy curves become flatter as the cluster size increases. This suggests that the affinity to form an ion pair decreases as more waters are added. Lastly, we began to see the formation of double minima in the potential energy curves at larger cluster sizes (n = 25, 28). The two minima correspond to intimate ion pairing and solvent-separated ion pairing. The solvent-separated ion pair is more stable than the intimate ion pair by approximately 20 and 18 kcal/mol for the n = 25 and 28 clusters, respectively
