摘要：

Vibrational spectra and LEED structures of CO on the Ru(001) surface were measured as a function of coverage at 100 K. The LEED patterns indicate that CO occupies a variety of asymmetric sites at high coverage, while the vibrational spectra show a single Ru-C stretching frequency (445 cm-1) and a single C-O stretching frequency (1980-2080 cm-1) at all coverages. This shows that on this surface the CO adsorption site at high coverages is determined by interadsorbate interactions, and that the carbon-oxygen stretching frequency is not site sensitive within the resolution of electron scattering measurements. © 1979 American Institute of Physics.
