Demodulation of multimodulation artifacts in Fourier-transform infrared spectroscopy [PDF]

open access: yes, 2017
Fourier-transform infrared (FTIR) spectra can show artifacts, for example, in the vicinity of the overtone when light is doubly modulated. Technical approaches, i.e., modifications to the spectrometer setup, have been devised in order to reduce those ...
