Webnormally in FTIR the baseline is on 100% which means the total transmission, except when we have a peak. but some times although we have no peaks, the base line … WebRemoving the baseline from the spectra, which are measured by a Fourier transform infrared spectrometer (FTIR), is an important preprocessing step for further spectra …
WebIt is possible to exclude spectral regions that do not contribute to the baseline from the fitting, while the baseline is used for the whole spectrum. This selection of appropriate spectral regions is essential for spc.fit.poly. But also spc.fit.poly.below can benefit from narrower spectral ranges: the fitting gains speed.
