Raman spectroscopic study of the mineral shattuckite Cu5(SiO3)4(OH)2
چکیده انگلیسی

Shattuckite Cu5(SiO3)4(OH)2 is a copper hydroxy silicate and is commonly known as a ‘healing’ mineral. Three shattuckite mineral samples from three different origins were analysed by Raman spectroscopy. Some Raman bands are common in the spectra of the minerals. Raman bands at around 890, 1058 and 1102 are described as the ν3 –SiO3 antisymmetric stretching vibrations. The Raman band at 670 cm−1 is assigned to the ν4 bending modes of the –SiO3 units and the band at around 785 cm−1is due to Si–O–Si chain stretching mode. Raman (and infrared) spectroscopy proves that water is in the molecular structure of shattuckite; thus the formula is better written as Cu5(SiO3)4(OH)2·xH2O.
