同分异构物的介电分析

Dielectric analysis of isomers

对一些甲苯族的结构与极性关系作了描述，并通过介电分析测定了同分异构物的介电谱。实验证明，介电分析是一种较简单有效的分析方法。用该方法可以得到其他化学方法所得不到的同分异构物的定性定量分析结果。

The relationship between structures and polarities of a number of nitrotoluenes is described. The dielectric spectra of isomers of nitrotoluene have been determined by dielectric analysis. Experimental results demonstrate that the dielectric analysis is a simple and effective method for qualitative and quantitative analysis of isomers, which is not possible with other chemical methods.
