The structure of the hydrotalcite desautelsite Mg6Mn2CO3(OH)16.4H2O has been studied by a combination of Raman and infrared spectroscopy. Three intense Raman bands are observed at 1086, 1062 and 1055 cm(-1). A model based upon the observation of three CO3 stretching vibrations is presented. The CO3 anion may be (a) non-hydrogen bonded, (b) hydrogen bonded to the interlayer water and (c) hydrogen bonded to the brucite-like hydroxyl surface. Two intense bands at 3646 and 3608 cm(-1) are attributed to MgOH and MnOH stretching vibrations. Infrared bands at 3476, 3333, 3165 and 2991 cm(-1) are assigned to water stretching bands. Raman spectroscopy has proven a powerful tool for the study of hydrotalcite minerals.
通过拉曼光谱和红外光谱相结合的方法研究了水滑石脱钙镁锰矿Mg6Mn2CO3(OH)16·4H2O的结构。在1086、1062和1055 cm(-1)处观察到三个强拉曼带。提出了一个基于观察到的三个CO3伸缩振动的模型。CO3阴离子可能是：(a) 非氢键结合的；(b) 与层间水形成氢键的；(c) 与水镁石型羟基表面形成氢键的。在3646和3608 cm(-1)处的两个强带归因于MgOH和MnOH的伸缩振动。在3476、3333、3165和2991 cm(-1)处的红外带被指定为水的伸缩带。拉曼光谱已被证明是研究水滑石矿物的有力工具。
