关于多基直链同系线性规律的研究已有报道,为了深入研究同系线性规律的量子化学基础,首先要弄清多基分子的轨道特性,文献已报道了这方面的工作。本文在前文的基础上,建立了轨道相点的概念,并得到了轨道相点分布的规律,发现了同系物中各分子的同类型轨道的相点有向某个中心凝聚的必然性。据此,对同系线性规律进行了理论上的证明。 It has been reported that the linear regularity of polycyclic linear homology has been reported. In order to further study the quantum chemical basis of homologous linear laws, we must first understand the orbital characteristics of poly-based molecules. The literature has reported this work. On the basis of the above, this paper establishes the concept of orbit phase point and obtains the rule of point distribution of orbit, and finds out the inevitability of the phase point of the same type of orbit of each kind of molecule in the homologue converging to a certain center. Based on this, the theory of homology linearity is theoretically proved.
