Infrared spectra of micronised goethite between 4000 cm-1 and 20 cm-1 were studied. Stretching and bending vibrations of structural hydroxy-groups were assigned using data on deuterated samples and comparison with α-Fe2O3 obtained by thermal decomposition.

Abstract
Infrared spectra of micronised goethite between 4000 cm-1 and 20 cm-1 were studied. Stretching and bending vibrations of structural hydroxy-groups were assigned using data on deuterated samples and comparison with α-Fe2O3 obtained by thermal decomposition. The existence of two different kinds of surface hydroxyls was also confirmed and an interpretation of their nature proposed. Various measured low-frequency bands were assigned to vibrations of the structural FeO6 blocks. © 1978.File in questo prodotto:
