用ENDOR法研究了双乙酰丙酮氧钒（IV）（VO（acac）2）配合物及其与甲醇和取代吡啶的加合物。测得的配体超精细分裂和四极耦合组件给一个详细的洞察到配合物的结构。实验数据使我们能够区分第六配体的可能结合位点。而甲醇显然绑定到空轴向位置，无论是顺式或反式异构体可以形成取代吡啶。我们的结果进行了比较与以前的红外研究。
The bis (acetylacetonato) oxovanadium (IV)(VO (acac) 2) complex and its adducts with methanol and substituted pyridines in frozen solution have been studied by ENDOR. The measured ligand hyperfinesplitting and quadrupole coupling components give a detailed insight into the structure of the complexes. The experimental data allow us to discriminate between possible binding sites of the sixth ligand. Whereas methanolevidently binds to the vacant axial position, either cis or trans isomers may be formed with substituted pyridines. Our results are compared with those of previous infrared studies.
