【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^′*、ε_π^*、ε_π^′*等键参数,并讨论了溶剂对配合物电子结构的影响.更多还原

【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 bondparameters 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.更多还原
