The structure of the kaolinite minerals; a FT-Raman study
Clay Minerals (March 1997) 32 (1): 65-77


The Fourier transform Raman spectra of the kaolinite minerals have been measured in the 50-3800 cm (super -1) region using near infrared spectroscopy. Kaolinites are characterized by remarkably intense bands in the 120-145 cm (super -1) region. These bands, attributed to the O-Si-O and O-Al-O symmetric bending modes, are both polymorph and orientation dependent. The 200-1200 cm (super -1) spectral range is a finger-print region for clay minerals and each kaolinite clay has its own characteristic spectrum. The structure of clays is fundamentally determined by the position of hydroxyl groups. Fourier-transform Raman spectroscopy readily enables the hydroxyl stretching region to be examined allowing identification of the component bands. The advantages of FT-Raman spectroscopy are shown to enhance the study of the kaolinite structure.
