VO(2+) doped single crystal of Ba(2)Zn(HCOO)(6)(H2O)(4) (BZFA) were investigated using electron paramagnetic resonance (EPR) technique at ambient temperature. Detailed investigation of EPR spectra indicated that the VO(2+) substitutes the Zn(2+) in the structure. The sites with different orientations were observed for VO(2+) in Ba(2)Zn(HCOO)(6)(H2O)(4).single crystal, but the only intense site among these sites was evaluated to obtain spin-Hamiltonian parameters, which are the principal axis values of the g and the hyperfine tensors. The covalent bonding parameter for VO(2+) and Fermi contact term were calculated using the spin-Hamiltonian parameters.
在室温下，使用电子顺磁共振（EPR）技术对VO(2+)掺杂的Ba(2)Zn(HCOO)(6)(H2O)(4)（BZFA）单晶进行了研究。EPR光谱的详细研究表明，VO(2+)取代了结构中的Zn(2+)。在Ba(2)Zn(HCOO)(6)(H2O)(4)单晶中观察到VO(2+)具有不同取向的位点，但对这些位点中唯一强烈的位点进行了评估，以获得自旋哈密顿参数，即g张量和超精细张量的主轴值。利用自旋哈密顿参数计算了VO(2+)的共价键参数和费米接触项。
