摘要：

Surface-extended x-ray-absorption fine-structure studies on the Ni(111)-c(4 X 2)-CO system show that CO adsorbs in threefold-coordinated hollow sites. This result is in conflict with the adsorption-site determination via molecular vibrational frequencies, which for this system led to an assignment of a bridge site.
