摘要: 为了研究无机物的理化性质与物质结构之间的内在联系‚利用原子价电子轨道能量 E i 和原子最外有效主量子数 n ∗i 组建点价值‚构建了一种新的价电子轨道能量拓扑指数( m Z) .用 m Z 的0‚1阶指数分别与无机氢化物的 pKa 1 值、20种碱金属卤化物的晶格能 U、生成焓Δ f Hθm 、水化能Δ f Gθm 和气态碱金属卤化物核间距 R 0 关联‚拟合所得的回归方程的相关系数(复相关系数)分别为0.9962(0.9966)、0.9966(0.9981)、0.9769(0.9830)、0.9768(0.9798)和0.9963(0.9963)‚所得结果较现有文献结果更为理想。

Abstract: In order to investigate the intrinsic relationship between the physicochemical property and the structure ofinorganic materials‚a new topological indexmZ of the valence electron orbit energy was proposed.This index was con-structed by the formation of point valence value which consisted of the valence electron orbit energy E i of the atom and the outermost effective main quantum number of atom n ∗i .The corresponding0-and1-rank indexes of m Z were then respectively fitted with the pKa 1 values of inorganic hydrides‚the lattice energy U‚formation enthalpyΔ f Hθm and hy-drated energyΔ f Gθm of20kinds of alkali halides‚and the internuclear distance R 0 of the gaseous alkali halides‚The re-lated coefficients(re-related coefficients) of the corresponding regression equations are respectively0.9962(0.9966)‚0.9966(0.9981)‚0.9769(0.9830)‚0.9768(0.9798) and0.9963(0.9963)‚the obtained results being better than those reported in the former literatures.
