A monolayer of N 2 O/Ni (111), a submonolayer species, and a monolayer of N 2 O/Ni (111)+ O p [2× 2] were studied using near-edge x-ray absorption fine-structure spectroscopy. From the polarization dependence we derive bent N 2 O molecules for the monolayer species whereas the two other species remain linear upon adsorption. Using the X α-scattered-wave method the polarization dependence of the three π* resonances was calculated explicitly for linear and bent N 2 O molecules. The calculations reproduced the experimental results quantitatively, yielding a bond angle of 165∘ for the monolayer species.
