摘要: 应用模糊数学方法处理13C-NMR谱数据,可以简便、准确、快速地解析某些有机化合物的结构。本文用择近原则和汉明距离鉴定了某些黄酮化合物;用模糊聚类分析测定了共轭双烯的构型;用模糊编网法区分了吡喃葡萄糖甲基甙的差向异构体。

Abstract: A treatment of 13C NMR data with fuzzy sets can help us to deduce the structures of some organic compounds. A few flavonoids were identified by the nearest neighbour technique and Hanmming distance;configurations of the conjugate dienes were determined by fuzzy classification;and the epimers of some methyl glucopyranosides were distinguished by fuzzy network.
