| Outline of Final Research Achievements |
We investigated successive adsorption and reaction of gas-phase free metal cluster ions with water molecules to obtain molecular-level insight into dissolution of substances in water and ice. The mechanism of hydration and subsequent reactions were revealed by successive reactions of aluminum cluster cations and mineral cluster anions with water molecules. Furthermore, mechanism of solvation and nitridation of group 5 metals by ammonia molecules were investigated by successive adsorption (solvation) of ammonia, which forms hydrogen-bond network, to tantalum cluster cations.
