Abstract

The orientation of thiophenol adsorbed on silver is determined by comparing ab initio calculated and experimental sum-frequency generation (SFG) spectra measured between 9 and 20 μm using a tandem KTP/ CdSe optical parametric oscillator. The molecule S-C bond is tilted ∼37° from the surface normal with the aromatic ring plane perpendicular to the surface.
