WebSimulation results show the first solvation shell of Na$\sp{+}$ and Cs$\sp{+}$ is filled by 6.2 and 10.5 methanols, respectively. These numbers are consistent with experimental results. The simulations also indicate that hydrogen bonding plays a significant role in shaping the solvent shell structure for both species. Web4 jun. 1998 · When a sodium ion is added it tends to lie in the center of the channel where it can form the most complete solvation shell. Its diffusion rate decreases in smaller channels until it moves too slowly in a channel of 2 Å radius to be detected in our simulations. This decrease is only partly due to an increase in the mean square force on the ion.
