摘要 以四氯化碳稀溶液中的(R)-1,3-丁二醇的聚集体系作为解析多聚体及其结构的模型.利用FSMWEFA(fixed-size moving window evolving factor analysis)结合PCA(principal component analysis),SIMPLISMA(simple-to-use interactive self-modeling mixture analysis)和ITTFA(iterative target transformation factor analysis)等分析方法对(R)-1,3-丁二醇溶液的红外光谱的组成进行分析,通过计算聚集度和平衡常数,确定(R)-1,3-丁二醇在惰性溶液中为单体-三聚体体系.同时运用密度泛函(DFT,density functional theory)对三聚体的结构进行解析,讨论了影响环形三聚体的结构因素.
