Arrangement of CO Molecules Adsorbed on Low Index Metal Surfaces : A Comparison between LEED and HREELS or IRS

  • J. P. Biberian
  • M. A. Van Hove


The adsorption of carbon monoxide on low index metal surfaces has been the object of intense research, presenting some apparently conflicting results. Thus, for three systems, CO on Cu(100), on Cu(111) and on Ru(0001), HREELS or IRS show only one C-O stretching frequency while an interpretation of the LEED diagram with a compact monolayer of CO gives at least two adsorption sites. A reexamination of these systems with a model based on a finite coincidence unit cell and one adsorption site, allows a better interpretation of all the data. Laser simulation of LEED is used to test this interpretation and to determine molecular positions within the larger coincidence unit cells.
