| 摘要: 本文研究了二(邻羟亚苄基胺)钒酰配合物在一系列有机溶剂中的ESR波谱。室温下,g值在不同溶剂中的变化有如下次序:CHCl3>py>CH3CN>THF>CH3OH,α值的趋势为:THF>CH3CN>CHCl3>py≈CH3OH.通过在THF及py溶剂中的低温ESR波谱得到的g11、g1、A11、A1、计算出了β2*2、K、β1*2、β1′*、επ*、επ′*等键参数,并讨论了溶剂对配合物电子结构的影响. |

| Abstract: Oxovanadium(IV) salicylaldimines have extensively been studied by ESR spectroscopy in a variety of organic solvents. At room temperature,g-value decreases in order: CHCl3,py,CH3CN,THF,CH3OH while α-value decreases in order: THF,CH3CN,CHCl3,py,CH3OH. From the spin Hamiltonian parameters obtained at low temperature,some bond parameters β2*2,κ,β1*2,β'*,επ*,επ'* have been calculated,and the effect of solvent on electron structures of the complexes has also been discussed. |
