摘要
利用计算机辅助分子异构体构建STRUauto算法,以解决高斯计算中分子结构独特性判断困难的问题.该算法借助能量和键长的迭代比较,完成分子结构的批量去重操作,避免了常规条件下分子结构独特性判断的误差,可得到准确的分子异构体.在几类典型分子结构上的实验测试结果表明,STRUauto算法能显著提高分子结构独特性判断的效率.
We used a computer aided molecular isomer constructionalgorithm STRU auto to solve the difficult problem of judging the uniqueness of the molecular structure in Gaussian calculation.With the help of the iterative comparison of energy and bond length,the algorithm completed the batch deduplication of the molecular structure,avoided the error of the judgment of uniqueness of the molecular structure under normal conditions,andobtained accurate molecular isomer.Experimental results on severaltypes of typical molecular structures show that the algorithm STRU auto can significantly improve the efficiency of judging the uniqueness of molecular structure.
