· J. Phys. Chem.; (United States)
The vibrational spectra of benzene, toluene, and pyridine adsorbed on Pd(111) have been measured by using the technique of electron energy loss spectroscopy (EELS). These three aromatics adsorb associatively at T = 180 K on this surface. At this temperature these molecules weakly bond to the surface with their ring planes oriented parallel to the surface plane. Only small shifts from liquid-phase frequencies are observed. At 310 K the bonding of pyridine to the surface appears to be predominately through the nitrogen lone pair. In addition, the authors compare the adsorption of these molecules on palladium to that on platinum, where there is a greater adsorbate-metal interaction.
