TL;DR: The results from surface vibrational spectroscopy have hitherto been interpreted in terms of CO adsorbing on threefold symmetric hollow sites in the R30° phase, but occupying bridge sites in c(4×2) phase.

TL;DR: A detailed quantitative structure determination of the Ni(111)c(4 × 2)-CO structure has been undertaken using scanned energy mode photoelectron diffraction from the C 1s state over a wide range of emission angles, and analyses of these data by approximate direct methods, and by two independent multiple scattering trial and error fitting optimisations lead to a consistent structure in which the CO occupies both types of hollow sites on the surface in equal amounts with a C-Ni top layer spacing of 1.29 ± 0.05 A.

TL;DR: The complete structural characterization of the surface acetate species on Cu{110} including independent determination of the sites of the two inequivalent carbon atoms is demonstrated.

TL;DR: The adsorption geometry of the surface methoxy species on Cu(111) has been determined quantitatively using scanned energy mode photoelectron diffraction in a two-step approach.

TL;DR: In this paper, the local adsorption structure of ammonia on Cu(110) was determined in a quantitative fashion using N 1s scanned-energy mode photoelectron diffraction, and the result is ascribed to adsorbate-adsorbate interactions (steric hindrance) similar to those found in (2 × 1)CO (pmg) structures seen on several fcc (110) surfaces, although in the case of ammonia, it occurs at coverages well below saturation, implying that ad-body attraction also occurs.
