| Research Abstract |
By means of pump-probe transient reflectance measurement using a femto-second pulse laser, we obtained real-time atomic motion of monolayer organic molecule films adsorbed on Au films and Ag nano-particles. This optical method demonstrate atomic-scale high sensitivity on ultrafast phenomena. In this technique, effectively applied was enhancement of electronic filed near the rough metallic surfaces and metal nanostructures through surface enhanced Raman scattering (SERS). With first principles calculation results, this real-time observation reveal propagation of plasmonic excitation of the metal via vibronic excitation of the molecular root to C-H vibration at the whole organic chain.
