摘要：

Raman spectroscopy has been used to characterize the antimonate mineral bahianite Al5Sb35+O14(OH)(2), a semi-precious gemstone. The mineral is characterized by an intense Raman band at 818 cm(-1) assigned to Sb3O1413- stretching vibrations. Other lower intensity bands at 843 and 856 cm(-1) are also assigned to this vibration, and this concept suggests the non-equivalence of SbO units in the structure. Low-intensity Raman bands at 669 and 682 cm(-1) are probably assignable to the OSbO antisymmetric stretching vibrations. Raman bands at 1756,1808 and 1929 cm(-1) may be assigned to delta SbOH deformation modes, while the bands at 3462 and 3495 cm(-1) are assigned to AlOH stretching vibrations. The complexity in the low wave number region is attributed to the composition of the mineral. Copyright (C) 2009 John Wiley & Sons, Ltd.
