The vibrational spectra of montmorillonites (SAz-2, STx-1, SWy-2 and Kunipia-F), obtained by Fourier Transform infrared (FT-IR) spectroscopy in the near (NIR) infrared region (8000 - 4000 cm-1) and in the middle (MIR) infrared region (4000 - 400 cm-1) together with Fourier Transform Raman (FT-Raman) measurements in the region from 4000 – 50 cm-1, will be presented. The aim of the experimental study was to compare the spectral data of both analytical techniques in terms of their sensitivity to chemical composition, isomorphic substitution of central atoms, and layer stacking order of the clay minerals. The results confirmed that FT-IR spectroscopy through MIR and NIR spectral regions provided the most comprehensive information about octahedral, tetrahedral and hydroxyl structure units of montmorillonites.
