Abstract

Our understanding of chemical bonding at surfaces has increased by using a variety of experimental techniques to study well-defined surfaces in high vacuum where surface impurities can be controlled. Studies of adsorption on these surfaces provide model systems that can be studied systematically to determine the evolution of molecular surface structure and bonding as environmental parameters are changed. A technique recently used to study chemical bonding on well-defined surfaces is normal unenhanced Raman spectroscopy (NURS). This technique was developed at the University of Kentucky, and it was used to obtain Raman spectra of molecules of low polarizability adsorbed on the non-enhancing metal surfaces Ni (111) and Ni(100). Raman signals from these adsorbates could be detected from one reflection off the metal surface. The technique is non-destructive of the surface species and low laser power (100–300 mW at the sample surface) is used.
