角分辨 XPS 是鉴定这些氮化学状态的深度分布情况的适当方法。 金属氮化物(例如 TiN)的 N1s 峰形可能复杂且特殊,可能存在表面氮氧化物。 对于 TiN 样品原样,其 N1s 区域的氧化氮化物状态对应的结合能比纯氮化物状态低。 氧化通常导致谱峰向高结合能方向位移(例如 NiSi 2 O 对比 NSi 3)。 N1s 和 Ta4p 3/2 区域之间的重叠可以通过峰拟合进行分离。 例如,在分析 TaN 时,这种方法很必要。 含氮的芳香族聚合物(例如,聚酰亚胺)可能产生较弱的 π-π* 卫星特征峰, …

The properties of nitrogen centres acting either as hydrogen-bond or Brønsted acceptors in solid molecular acid-base complexes have been probed by N 1s X-ray photoelectron spectroscopy (XPS) as...
Origins of peaks of graphitic and pyrrolic nitrogen in N1s X-ray ...
2021年7月12日 · X-ray photoelectron spectroscopy (XPS) is among the most powerful techniques to analyse structures of nitrogen-doped carbon materials. However, reported assignments of (1) graphitic nitrogen (N)/substitutional N, quaternary N (Q–N), or tertiary amine (T–N) and (2) pyrrolic N/secondary amine or T–N are questionable.
