The structure of NH[sub 3] adsorbed on the Ni(100) surface was studied using the angle-resolved photoemission extended fine-structure (ARPEFS) technique. The ARPEFS data were taken along the surface normal-emission direction at a sample temperature of 100 K. Multiple-scattering spherical-wave data analysis determined that NH[sub 3] adsorbs at the atop site of the Ni(100) surface with a N-Ni bond length of 2.01 A and a 2.8% expansion of the topmost Ni-Ni interlayer spacing.
