Abstract
The use of infrared-FEL allows adsorbate vibrational spectroscopy by I R-visible sum-frequency generation (SFG) beyond the frequency range ac cessible by benchtop IR lasers. Therefore, we synchronized a frequency doubled mode-locked YAG laser (532 nm) with the CLIO-FEL, which is tu neable from 2 to 17.5 mum. The feasibility is demonstrated by recordin g SFG-vibrational spectra near 5-mum of the CO adsorbate at the electr ochemical interface Pt/HClO4 Solution containing CH3OH. These spectra indicate the coexistence of linearly and doubly-bounded species. This work is a preliminary step towards adsorbate SFG-vibrational spectrosc opy at longer wavelengths.
