Abstract
Chemical shift photoelectron diffraction has been applied to the model system of coadsorbed PFx(x=1,2,3) species on Ni(111), produced by electron beam fragmentation of a PF3 overlayer, to determine quantitatively and independently the local adsorption site of each species. PF3 is found to occupy atop adsorption sites above the outermost Ni layer atoms at a P-Ni bond length of (2.07 +/- 0.05) angstrom, PF2 occupies bridge sites at a spacing of (1.70 +/- 0.05) angstrom, while the PF species occupy both types of threefold coordinated hollow sites, maintaining a constant P coordination throughout the fragmentation.
