摘要: 以图论为基础,从化合物的二维连接表出发,在环识别算法的约束下,对分子中的节点进行判断。结果表明,该算法能够识别大多数化合物中的芳香性。作为约束条件,把芳香性的识别算法应用于ESESOC系统中结构的穷举生成,得到了较好的结果。

Abstract: It is important to detect the aromaticity of structures during the process of structure elucidationand output.In this paper, an alogrithm was proposed to detect the aromaticity of structures by the use ofalgorithm on ring identification.The results show that it could be used to identify most of the aromaticstructure.It have been used as constraints of Expert System on Elucidation Structure of Organic Com-pounds(ESESOC) and a good result has been achieved.
