Abstract

In order to elucidate the chemical composition, stability, and nature of atmospheric ions, extensive studies of the thermodynamic properties of molecular clustering about ions have been undertaken in our Laboratory. Significant new findings show that the bond energies for polar molecules clustered about ions of open electronic structure are far greater than expected for a simple ion-dipole interaction. The results clearly establish the fact that chemical bonding is quite important in effecting the formation of atmospheric ions. These results have also led to a clarification of the role of small clusters in ion-induced nucleation phenomena.
