烷烃的折光率与分子结构间的定量关系

The quantitative relationship between alkane refractive index and its molecular structure

以碳原子数 N和 Wiener指数 W,P为结构参数 ,通过数学拟合的方法 ,建立了烷烃的折光率与其分子结构间的定量关系式 ,并计算了 1 0 1个烷烃的折光率。结果表明 ,该式计算结果较准确 。

This paper,using the number \%N\% of carbon atoms and Wiener index \%W,P\% as structural parameters,established a quantitative relationship formula between refractive indexes of alkanes and its molecular structure.The refractive indexes of 101 alkanes were calculated.The results show that the calculated results of the formula are quite accurate and that the formula possesses a certain theoretical significance.The formula can be used to forecast refractive indexes of alkanes.
