Infrared (IR) spectroscopic studies of mineral and synthetic phosphates have been presented. The interpretation of the spectra has been preceded by the isolated PO(4) tetrahedron spectra analyse. The K(3)PO(4) saturated aqueous solution was measured in the special cell for liquids. The obtained IR results have been compared with the theoretical number of IR-active modes. The number and positions of the bands due to P-O vibrations have been established. The phase composition of the phosphates has been determined using XRD and IR spectroscopy methods. The influence of non-tetrahedral cations on the shape of the spectra and the positions of bands has been analysed and the crystalline field splitting effect has been discussed.
红外（IR）光谱研究了矿物和合成磷酸盐。在分析孤立的[PO（4）]（3-）四面体光谱之前，对光谱进行了分析。在特殊的液体池测量了 K（3）PO（4）饱和水溶液。将获得的 IR 结果与理论 IR 活性模式数量进行了比较。确定了由于 P-O 振动引起的带的数量和位置。使用 XRD 和 IR 光谱法确定了磷酸盐的相组成。分析了非四面体阳离子对光谱形状和谱带位置的影响，并讨论了晶场分裂效应。
