Ultraviolet reflection–absorption spectroscopy of benzene on metal surfaces

Abstract
This article reports on ultraviolet reflection–absorption spectroscopy of C6H6 molecules physisorbed on Ag, Cu, and Au surfaces. The electronic 1A1g→1B2u transition of C6H6 at wavelengths near 250 nm is observed. We model the system and obtain center frequencies, linewidths, and estimates of the oscillator strengths for the various vibronic absorptions.
