摘要
在Randic分子价连接性拓扑指数的基础上,构建了价电子轨道平均能量拓扑指数mT 用其0,1阶指数0T,0T和1T以及Pauling电负性差的平方分别与P区无机氢化物的pKa1值关联,拟合成3个回归方程,其相关系数分别为0.9958,0.9960和0.9965,结构选择性达到唯一性表征
Based on the topological index of Randic molecular connection, the authors construct the topological index mT averagy energy of valence electron orbit. Utilizing the link between its 0T, 0T and1T,0T and (χA-χH)2 and pKa1 of inorganic hydride in p area, the paper suggests 3 linear equations. The related coefficient difference is 0.9958, 0.9960 and 0.9965. The structure selectivity of topological index is unique. Hence the calculation gains better results.
