摘要

Raman and infrared spectra of two well-defined fluellite samples, Al_2(PO_4)F_2(OH)·7H_2O, from the Krásno near Horní Slavkov (Czech Republic) and Kapunda, South Australia (Australia) were studied and tentatively interpreted. Observed bands were assigned to the stretching and bending vibrations of phosphate tetrahedra, aluminum oxide/hydroxide/fluoride octahedra, water molecules and hydroxyl ions. Approximate O-H…O hydrogen bond lengths were inferred from the Raman and infrared spectra.
