Web17 dec. 2024 · Multiplicative Scatter Correction in Python MSC requires a reference spectrum to start with. The reference spectrum is ideally a spectrum free of scattering effects. 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 ...
