Web30 aug. 2024 · Multiplicative scatter correction (MSC) is a widely used classic normalization technique to correct spectra in such a way that they are as close as possible to a reference spectrum. In IDCube the reference spectrum is the mean of the selected area. MSC requires a reference spectrum. This is the most important difference between MSC … WebMultiplicative scattering correction (MSC) or derivation can eliminate these variations [117, 118]. [Pg.219] Compared to spectra obtained in the mid- infrared region, NIR spectra contain fewer, less resolved, peaks. Due to scattering and other effects, a set of NIR spectra on similar samples often exhibits constant baseline offsets from one to ...
