Descrição: dc.descriptionThis research was undertaken on phosphophyllite sample from the Hagendorf Süd pegmatite, Bavaria, Germany. Chemical analysis was carried out by Scanning Electron Microscope in the EDS mode and indicates a zinc and iron phosphate with partial substitution of manganese, which partially replaced iron. The calculated chemical formula of the studied sample was determined to be: Zn2(Fe0.65, Mn0.35)P1.00(PO4)2- .4(H2O). The intense Raman peak at 995 cm^-11 is assigned to the m1 PO4^3- symmetric stretching mode and the two Raman bands at 1073 and 1135 cm^-1 to the m3 PO4^3- antisymmetric stretching modes. The m4 PO4^3- bending modes are observed at 505, 571, 592 and 653 cm^-1 and the m2 PO4^3- bending mode at 415 cm^-1. The sharp Raman band at 3567 cm^-1 attributed to the stretching vibration of OH units brings into question the actual formula of phosphophyllite. Vibrational spectroscopy enables an assessment of the molecular structure of phosphophyllite to be assessed.-
