用XRD、FTIR、固体NMR和ESCA对铝羟乙酸钡（Ba[Al 2（C2 H4 O2）4 ]）进行了详细的研究。在含有6-和4-配位Al的化合物的结合能之间，该材料存在一组独特的ESCA芯能级结合能。NMR检测到在“蒸馏”Ba-Al V化合物中存在6-配位Al杂质，但是含有5-和6-配位Al的化合物的Al（2 p）峰太接近而不能通过ESCA分辨
A detailed study of barium aluminate glycolate, Ba[Al 2 (C 2 H 4 O 2 ) 4 ], a compound in which aluminum is in 5-coordination with respect to oxygen has been carried out using XRD, FTIR, solid-state NMR, and ESCA. There is a unique set of ESCA core-level binding energies for this material, between those for compounds containing 6- and 4-coordinate Al. NMR detects the presence of a 6-coordinate Al impurity in the «distillation» Ba-Al V compound, but the Al(2p) peaks for compounds containing 5- and 6-coordinate Al are too close to be resolved by ESCA
