本文研究了ＶＯ（Ⅱ）－苯甲酰异羟肟酸配合物在一系列溶剂中室温和低温下的ＥＳＲ波谱，讨论了不同溶剂对常温下各向同性波谱的线宽和超精细分裂常数的影响。通过测定不同溶剂中的低温各向异性ＥＳＲ波谱得到的ｇ＿（１１），ｇ＿⊥，Ａ＿（１１），Ａ＿⊥等波谱参数，结合电子光谱测定的ｄ－ｄ跃迁数据，计算出α￣２，Ｋ，β￣２，γ￣２等键参数，并讨论了溶剂对配合物电子结构的影响。
In this paper, ESR spectra of VO (Ⅱ) -benzoylhydroxamic acid complexes at room temperature and low temperature in a series of solvents were studied. The effects of different solvents on the linewidth and hyperfine splitting constants of isotropic spectra at room temperature influences. By measuring the spectral parameters of g_ (11), g_⊥, A_ (11) and A_⊥ obtained by low temperature anisotropic ESR spectroscopy in different solvents and combining the d-d transition data determined by electron spectroscopy, α ~ 2, K, β ~ 2, γ ~ 2 and other key parameters, and discussed the impact of solvents on the electronic structure of the complex.
