计算机分解三元混合物的IR光谱

Computer Resolution of Infrared Spectra of Ternary Mixtures

利用混合物的比值光谱并结合“谱图扣减”技术建立了用于未知组成的混合物分析的方法,采用矩阵数学形式表达,简化了操作,并可用于任何多元体系。用此方法分析液、固及聚合物等不同状态的三元混合物均取得了满意的结果。

A general spectroscopic method for analysis of unknown mixtures was firstmentioned by Hirscheld and Koenig.The method was based on“spectrum strip-ping”in the general case of a mixture of unknown concentrations of an unknownnumber of unknown constituents.This report deals with an application of the method to ternary mixtures whichcan be liquid,solid and polymer,etc.The problems that may arise in the applica-tion of the procedure are discussed.The procedure involves an array matrix inversion and recognizable spectra ofmathematically separated constituents are constructed.
