Outline of Final Research Achievements

Many of the important issues in the field of nuclear energy are deeply related to chemical reactions occurring at the two-phase interfaces of solid, liquid and gas. However, it is difficult to directly obtain microscopic information on the chemical reactions occurring at the interfaces with conventional experimental methods. In the present study, we adopted an advanced second-order nonlinear vibrational spectroscopic technique, i.e., heterodyne-detected vibrational sum-frequency generation spectroscopy (HD-VSFG), and this enabled us to study the atomic and molecular structures at the interfaces related to solvent extraction separation and actinide chemistry, etc. that are significant in the field of nuclear energy.
