偶极矩的测量在最近三十多年以来对于研究分子结构,特别是有机化合物的分子结构,起了一定的作用。大家都知道,为了计算偶极矩,必须求得下列实验值:介电常数、密度、折射率与浓度等,其中后三项较易测定,而介电常数则需要特殊仪器。本文扼要介绍一些测量偶极矩的方法,以供读者参考。 The measurement of dipole moment has played a certain role in the study of molecular structure, especially the molecular structure of organic compounds, for more than three decades. As we all know, in order to calculate the dipole moment, we must find the following experimental values: dielectric constant, density, refractive index and concentration, of which the latter three easier to determine, and the dielectric constant requires special equipment. This article briefly introduces some methods of measuring dipole moments for your reference.
