直链1—溴烷烃结构与折光指数关系的探讨

Quantitative Study on the Relationship Between Refractive Index and Molecular Structure of Normal 1- Bromoalkane

根据分子拓扑学原理．用拓扑方法探讨了直链１—溴烷烃的折光指数与其分子结构之间的关系，提出一个结构基础明确的定量关系．应用这一定量关系．不仅能够表征直链１－溴烷烃结构与折光指数之间的关系，而且能够预测折光指数．结果表明，折光指数预测值都接近实验值．平均误差０．０５３％．

An approach based Oil the molecular topology is used to study the relationship between refractive index and molecular structure of normal 1 - bromoalkane.and a quantitative relation is developed which can be used to charcterize the structure-property relationship and to predict the refractive indexes of normal 1- bromoalkanes. The calculated results show that the predicted values of refractive indexes are in good agreement with the experimental data .and the mean relative deviation is 0. 053%. Not only can the quantitative relation predict the refractive indexes of normal 1- bromalkanes but can help to discover the secret among the structure- property relationship.
