Title
Solvation shell dynamics of Na+ and Cl− ion pairs in selected water-DMSO mixtures
Abstract
We have investigated the solvation shell dynamics of Na+ and Cl- ion pairs in water - DMSO mixtures of three compositions with x(DMSO) (mole fraction of DMSO) = 0.21, 0.35 and 0.48. Dynamical ion pair trajectories in these compositions are studied to analyze the diffusional behaviour of the solvent molecules in the primary and secondary solvation shells as well as the bulk solvent. As expected, the diffusivity of the primary solvation shells is smaller than the bulk. The insertion of solvent molecules in the region between the ion pairs during the ion pair separation process is analyzed from the classical ion pair molecular dynamics trajectories in these compositions of water DMSO mixtures.
