| 摘要: 钇对苯甲酸芳香体系的效应加以研究并与碱和碱土金属以及若干过渡金属和有毒的重金属的效应相比较。钇与镧系元素相似,具有稳定苯甲酸体系的效应。芳香体系的微扰作用随着金属离子势的减小而增大。红外谱带强度的详细分析表示钇的位置是在铒与铥之间。芳香环谱带的相对强度和频率对于镧系元素原子序数的依赖关系表明双-双效应的存在。 |

| Abstract: The effect of yttrium on the aromatic system of benzoic acid was investigated and compared with the effect of selected transition, alkaline and alkaline earth metals, as well as of some heavy toxic metals. Yttrium, like lanthanides, stabilizes the aromatic system of benzoic acid. The perturbation of the aromatic system increases with decreasing ionic potential of the metals. A detailed analysis of intensity of IR bands showed that the position of yttrium is situated between erbium and thulium. The dependence of relative intensity and frequency of bands of aromatic ring on the atomic number of lanthanides indicates the presence of a double-double effect. |
