-
摘要: 本文用原子的半径-电荷比定义原子结构参数Pi和分子结构参数P.用P分别研究了含氢分子SiHmXn和CHmXn (X =F, Cl, Br, I) 的标准生成焓, 二者呈良好的线性关系.本文的定义考虑了氢对分子结构和性质的贡献Abstract: The atomic and molecular structure parameters Pi and P are defined as: Pi=
. The correlation relationships between P and the standard formation enthalpies of SiHmXn, CHmXn (X=F, Cl, Br, I) are studied showing the correlation coefficients 0.976 5, 0.975 2, respectively.-
Key words:
