对无机磷酸盐晶体中P2p、P2 s和O 1 s芯能级发射的光电子结合能进行了大量的实验研究，并以能量差Δ（O 1 s-P2p）和Δ（O 1 s-P2 s）作为最稳健的特征参数进行了比较。结合能差与磷原子和氧原子之间的平均化学键长L（P-O）呈线性关系，其函数为：Delta（O 1 s-P2p）（eV）= 375.54 + 0.146。L（P-O）（pm）和Delta（O1s-P2s）（eV）= 320.77 + 0.129。L（P-O）（pm）.的依赖性是一般的无机磷酸盐和可用于定量成分分析的X射线光电子能谱的复杂的氧化物化合物，包括功能团与不同的协调的P和O原子。
Wide set of experimental results on binding energy of photoelectrons emitted from P 2p, P 2s, and O 1s core levels has been observed for inorganic phosphate crystals and the parameters were compared using energy differences Delta(O 1s - P 2p) and Delta(O 1s - P 2s) as most robust characteristics. Linear dependence of the binding energy difference on mean chemical bond length L(P - O) between phosphorus and oxygen atoms has been found. The functions are of the forms: Delta(O 1s - P 2p) (eV) = 375.54 + 0.146 . L(P - O) (pm) and Delta(O 1s - P 2s)(eV) = 320.77 + 0.129 . L(P - O) (pm). The dependencies are general for inorganic phosphates and may be used in quantitative component analysis of X-ray photoemission spectra of complex oxide compounds including functional groups with different coordination of P and O atoms.
