【摘要】 基于距离矩阵和邻接矩阵定义了一种新的拓扑指数———nχda,与乙烷至壬烷的74个化合物的10种物性进行了关联,并与W、1χ、I指数进行了对比,除蒸发焓和溶解度外均以1χda为最优.更多还原

【Abstract】 A new topological index was defined according to the distance matrix and adjacent matrix. The indices of n χda ,W, 1 χ and I were respectively correlated with ten chemicalphysical properties of 74 alkenes from ethane to nonane. The results indicated that 1 χda is the best index except solubility and enthalpy of vaporization.更多还原
