| Outline of Final Research Achievements |
It is believed that relatively weak interactions such as electrode/molecule interactions, intermolecular interactions, and hydrogen bonding play important roles in electrochemical reactions. If surface sensitive vibrational spectroscopy is conducted in so-called terahertz frequency region, we can obtain such information, which helps our understanding of the reaction mechanisms. In this project, we extended the detectable range of surface enhanced Raman scattering (SERS) spectroscopy and observed metal surfaces under electrochemical conditions. We successfully observed large amplitude bending motions of molecular adsorbates. We also applied this technique to single crystalline gold surfaces and demonstrated that this ultra-low frequency SERS spectroscopy was indeed sensitive to atomic surface structures.
