[3F01]In-situ terahertz spectroscopy based on surface-enhanced Raman scattering as a tool for studying electrode-electrolyte interfaces
*Katsuyoshi Ikeda1 (1. Nagoya Institute of Technology)
Surface-enhanced Raman scattering (SERS) is widely recognized as a powerful spectroscopic tool for studying electrode-electrolyte interfaces at the molecular level. However, SERS spectroscopy is normally operated in the so-called vibrational fingerprint region between 400 – 1600 cm-1 where intramolecular vibrations are observed. When the detectable frequency range of SERS is extended into the low frequency region below 300 cm-1, intermolecular weak interactions such as hydrogen bonding can also be detected. In this talk, SERS observation at various electrolyte-metal interfaces is demonstrated in the wide frequency range between 10 – 4000 cm-1.
