扫描能量模式N和O 1 s光电子衍射数据收集从NO在Ni（111）的条件下，对应于三个不同的N-O振动频率，以前分配给不同的（桥和顶部）的本地吸附配置，表明NO在所有情况下占据相同的网站。这些数据与理论模拟结果的比较表明，共同的网站是一个三重协调空心。这些结果表明，有必要重新评估广泛使用的方法的适用范围内的内部分子振动频率的数值的基础上的吸附位点分配。
Scanned energy mode N and O 1s photoelectron diffraction data collected from NO on Ni(111) under conditions corresponding to three distinct N-O vibrational frequencies, previously assigned to different (bridge and atop) local adsorption configurations, show that NO in all cases occupies the same site. Comparison of these data with the results of theoretical simulations indicates that the common site is a threefold coordinated hollow. These results indicate that there is a need to reevaluate the range of applicability of the widely used method of adsorption site assignment based on the numerical values of internal molecular vibrational frequencies.
