Planchéite Cu(8)Si(8)O(22)(OH)(4)·H(2)O is a hydrated copper hydroxy silicate. Raman spectroscopy complimented with infrared spectroscopy has been used to determine the molecular structure of planchéite. Raman bands at around 1048, 1081 and 1127 are described as the ν(1)-SiO(3) symmetric stretching vibrations; Raman bands at 828, 906 are attributed to the ν(3)-SiO(3) antisymmetric stretching vibrations. The Raman band at 699 cm(-1) is assigned to the ν(4) bending modes of the -SiO(3) units. The intense Raman band at 3479 cm(-1) is ascribed to the stretching vibration of the OH units. The Raman band at 3250 cm(-1) is evidence for water in the structure.
水羟硅铜钙石（Planchéite Cu(8)Si(8)O(22)(OH)(4)·H(2)O）是一种含水的铜羟硅酸盐。拉曼光谱与红外光谱相结合，用于确定水羟硅铜钙石的分子结构。1048、1081 和 1127 处的拉曼带被描述为 ν(1)-SiO(3)对称伸缩振动；828 和 906 处的拉曼带归因于 ν(3)-SiO(3)反对称伸缩振动。699 cm(-1)处的拉曼带被分配给-SiO(3)单元的 ν(4)弯曲模式。3479 cm(-1)处的强拉曼带归因于 OH 单元的伸缩振动。3250 cm(-1)处的拉曼带证明了结构中的水。
