The kaolinite‐like phyllosilicate minerals bismutoferrite BiFe 3+ 2 Si 2 O 8 (OH) and chapmanite SbFe 3+ 2 Si 2 O 8 (OH) have been studied by Raman spectroscopy and complemented with infrared spectra. Tentatively interpreted spectra were related to their molecular structure. The antisymmetric and symmetric stretching vibrations of the SiOSi bridges, δ SiOSi and δ OSiO bending vibrations, ν (SiO terminal ) − stretching vibrations, ν OH stretching vibrations of hydroxyl ions, and δ OH bending vibrations were attributed to the observed bands. Infrared bands in the range 3289–3470 cm −1 and Raman bands in the range 1590–1667 cm −1 were assigned to adsorbed water. OH···O hydrogen‐bond lengths were calculated from the Raman and infrared spectra. Copyright © 2009 John Wiley & Sons, Ltd.
