High resolution electron energy loss spectroscopy (HREELS) has emerged over the past decade as a sensitive and versatile surface analysis technique that can be used to study surface vibrations at an unprecedented level. The most important application of this technique has been to characterize atoms and molecules adsorbed on single crystal metal surfaces. In this paper, the physical basis for the HREELS technique and the interpretation of vibrational spectra to identify surface species and adsorption geometries are discussed. Recent studies of hydrocarbon adsorption and decomposition are reviewed to illustrate the use of HREELS in studies of the molecular structure of adsorbed monolayers.
