Calculation of Properties of Ionic Water Clusters by the MNDO Method
Airborne ions created by cosmic rays and earth radioactivity can be subject to hydration. Hydrated ion clusters are of great atmospheric importance, e.g. in regards to atmospheric electricity and ion nucleation. Computed results for the heats of formation and the entropy changes for small ion water clusters H3O+ (H2O)n are reported in comparison with observations and ab initio calculations. Despite the exclusion of hydrated ion clusters in the procedure of parameterization in our earlier modified treatment of MNDO (modified neglect of differential overlap) specifically for treating water clusters (H2O)n, computed results of the hydrated ion clusters are in reasonable agreement with observation and ab initio calculations.
