Structural Chemistry（Ohashi Lab.）

Molecular clusters and cluster ions are useful model systems for investigating intermolecular interactions at the microscopic level. Our group has been studying structures and dynamics of molecular clusters and cluster ions through spectroscopic experiments and theoretical calculations. Currently, we focus on the interaction between metal ions and solvent molecules. Our research subjects include (1) coordination and solvation structures of transition metal ions, (2) cooperation and competition between metal ion–solvent and solvent–solvent interactions, (3) comparison of coordination numbers between ions in the gas phase and in bulk solutions, (4) temperature effects on prevalent structures of solvated metal ions, (5) interaction of metal ions with biologically relevant molecules, and so forth.
