摘　　要：优化迭代目标转换因子分析法在多组分混合物红外光谱解析中的应用何锡文，陈鼎，王永泰（南开大学化学系、中心实验室，天津，３００００７１）关键词因子分析，相关性，红外光谱因子分析是一种多元统计方法，用其解析多组分混合物的红外光谱已有报道［１，２］。迭代目标...Based on the iterative target transformation factor analysis(ITTFA),a series of steps are taken to improve the component resolution function.These steps include the selection of an optimum set of wavenumbers and the selection of an optimum standard concentration matrix.This method can minimize the correlation of components obviously, so it is very useful to resolving the systems which are composed of spectra overlapped components.Three component system of o,m,p-chlorotoluene is presented in this paper.Satisfactory results are obtained.The influences of baseline correction and resolution on the calculated results are also discussed in detail.
