The processes of dehydration and rehydration of montmorillonite and nontronite samples have been studied through infrared absorption spectra.

The changes observed in the intensity of the bands during dehydration show the analogy between absorption at 915 cm-1 (montmorillonite) and at 820 cm-1 (nontronite), their origin being a deformation vibration of OH groups.

During rehydration of the montmorillonite sample, the recovered OH groups occur in two different forms, in accordance with the results of differential thermal analysis.
