摘要
基于核磁共振现象定义一个新的拓扑指数Ω.以沸点T和Ω建立回归方程:ln(955-T)=6.822-0.07Ω;R=0.999,S=0.0066647,F=36656.45,n=85.计算值与实验值非常吻合,表明Ω具有良好的相关能力和结构选择性.
A novel topological index Ω based on the phenomenon of nuclear magnetic resonance is derived in this paper.Then the regression equation is set up with boiling point T andΩ:ln(955-T)=6.822-0.07Ω;R=0.999,S=0.0066647,F=36656.45,n=85.The calculated values are in excellent agreement with the experimental values.The result suggests that topological index Ω has good high correlation ability and structural selectivity.
