The Raman spectra of pseudolaueite, strunzite, ferrostrunzite and ferristrunzite have been obtained at 298 K using Raman microscopy. These spectra are compared with their infrared spectra. The vibrational spectra of the four minerals are different, in line with differences in crystal structure and composition. Some similarity in the Raman spectra of the hydroxyl-stretching region exists, particularly but characteristic differences in the OH deformation regions are observed. Differences are also observed in the phosphate stretching and deformation regions.
This paper offers new knowledge and understanding of the mineral pseudolaueite of formula Mn2+Fe2 (3+)(PO4)(2)(OH)(2)center dot 8H(2)O,a hydrated hydroxy phosphate of ferric iron and manganese.
