应用气液色谱和分子模型相结合的方法,研究了各种化合物之间的分子间引力,发现在某些分子上可含有几个略带正电荷的氢原子所构成的正电集团,或几个带负电的原子所构成的负电集团,或由正负中心所构成的正负集团。当二分子上的集团结构互相适应(电子性质适应和空间结构适应)时,此等集团之间即可呈现出很强的作用力且有很高的选择性,从而导致许多物理性质的反常现象。 The gas-liquid chromatography and molecular model are combined to study the intermolecular attraction among various compounds. Some molecules can be found to contain positive groups of several positively charged hydrogen atoms, Negatively charged atoms formed by the negative group, or positive and negative center formed by the positive and negative groups. When the two groups’ structures are adapted to each other (the adaptation of electronic properties and the adaptation of the spatial structure), these groups can show strong force and high selectivity, resulting in many anomalies of physical properties .
