Nonlinear least-squares fitting of multivariate absorption data

The introduction of fast scanning and diode-array spectrophotometers facilitates the acquisition of large series of absorption spectra as a function of reaction time (kinetics), elution time (chromatography), or added reagent (equilibrium investigations). It is important to develop appropriate programs that are able to handle the wealth of data and to extract all information. In this contribution a new application of factor analysis in a nonlinear least-squares fitting algorithm is presented
