Analysis of Correlated Spectral Data

We describe a program for analyzing correlated spectral data by Procrustes rotation, which eliminates the need for reference samples (Kubista, M. Chem. Intel. Lab. Syst. 1990 7, 273). The experimental spectra are the only input required by the DATa ANalysis (DATAN) program, which calculates the number of components, their spectral profiles, their concentrations, and the ratio of their responses to two spectroscopy measurements
