Relative stabilities of the different geometries are also affected by the change of the dielectric constant, as is shown in Figure . Although the effect is not very strong, we find a slight variation in the values of ∆∆E T/O as the dielectric increases, which suggests that for higher values of the dielectric, octahedral clusters are slightly less favored. Overall, the results obtained with different dielectric constants show that both the relative stabilities of the clusters and their preferred geometries change gradually depending on the exposure to the solvent.
