Ion-tetrad relative distance distributions and core-ion clusters show the position of the bound ions in the tetrad core. All distributions are centered on the tetrad core center of mass (relative distance = 0 Å). Ion-tetrad relative distances for all replicates were combined to produce distributions for KCl, NaCl, and LiCl. Cartoon renderings of the top tetrad core-ion cluster in each ion type (right) to illustrate common local alignment in these systems.
