Abstract
Recently, a new multivariate analysis tool was developed to resolve mixture data sets, where the contributions ('concentrations') have an exponential profile. The new approach is called DECRA (direct exponential curve resolut ion algorithm). DECRA is based on the generalized rank annihilation method (GRAM). Examples will be given of resolving nuclear magnetic resonance spec tra resulting from a diffusion experiment, spectra in the ultraviolet/visib le region of a reaction and magnetic resonance images of the human brain.
