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。
The effect of yttrium on the benzoic acid aromatic system was studied and compared with the effects of alkali and alkaline earth metals and several transition metals and toxic heavy metals. Yttrium is similar to lanthanides and has the effect of stabilizing the benzoic acid system. Perturbation of the aromatic system increases with decreasing metal ion potential. A detailed analysis of the intensity of the infrared band indicates that the position of yttrium is between erbium and gallium. The dependence of the relative intensity and frequency of aromatic ring bands on the atomic numbers of the lanthanide elements indicates the existence of a double-double effect.
