分子拓扑指数在氢化物中的应用——S区氢化物物理化学性质递变规律的研究
Application of Topological Index in Inorganic Hydrides ——study on the progressive changes of physicochemical properties of S block Hydride
【摘要】 根据Randic的分子连接性拓扑方法,提出了一个新的分子拓扑指数YM,将S区氢化物HnA(n=1,2)的物理化学性质Pi与分子拓扑指数YM相关联,复相关系数优良,标准偏差小,计算结果与实验值很吻合。
【Abstract】 On the basis of Randic’s molecular connectivity indesc,a new topological index Y M was propsaled. A linear regeession equations of the relationship between physicochemical properties P i and topological inder Y M of ion hydrides with high correlation coefficients can be used for the accurate descriptios of the propressive changes of physicochemical properties of halogenides of S block hydrides.
