Abstract

Abstract: 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.
