Molecular dynamics simulations have been carried out for Sr2+ in methanol using different Sr2+ Lennard-Jones parameters and methanol models. X-ray absorption fine structure. (EXAFS) spectroscopy has been employed to assess the reliability of the ion-ion and ion-methanol potential functions used in the simulations. Radial distribution functions of Sr2+ in methanol have been. calculated for each simulation and compared with the EXAFS experimental data. This procedure has allowed the determinations of reliable Sr2+-methanol models which have been used in longer simulations providing an accurate description of the dynamic and structural properties of this system.
