General α_N Index and Its Application Ⅱ. The Correlation between the General α_N Index and Physical Properties of Neutral Phosphorus Compounds

前文提出了一般有机分子的广义α_N指数的概念,建立了计算分子广义α_N指数的方案.在此基础上,本文将中性磷萃取剂的广义α_N指数用于其密度、折光率、纸上层析比移值以及磷氧键红外特征频率等物理性质的研究,取得了满意的相关结果,说明这种能分辨有微小结构差异的广义α_N指数是反映分子性质的一个良好的拓扑指数.

The relationship between the α_N index and phygical properties of neutral phosphorus extractants ig studied. Using the general α_N index which could describe extractants with minute difference in structure, the good correlation between it and various physical properties of the neutral phosphorus extractants (e. g., densities, refractive index, shift ratio of paper chromatography and IR frequencies of bond P=O) is obtained. The result indicates that general α_N index is a good topological index of organic compounds.
