Hydrated cesium borates have been synthesized by the reaction of Cs(2)CO(3) with H(3)BO(3) aqueous solution. After reaction equilibria were reached, liquid and solid phases were separated and the FT-IR difference and Raman spectra of each phase were recorded, respectively. The assignments of the recorded FT-IR absorption frequencies and Raman shift are given. The main polyborate anions and their interaction in borate aqueous solution have been proposed. The relations between the existing forms of polyborate anions and the crystallizing solid phases, Cs(2)B(4)O(7).5H(2)O and CsB(5)O(8).4H(2)O, have been gained.
通过碳酸铯与硼酸水溶液反应合成了水合硼酸铯。反应达到平衡后，将液相和固液相分离，并分别记录各相的傅里叶变换红外（FT-IR）差谱和拉曼光谱。给出了所记录的FT-IR吸收频率和拉曼位移的归属。提出了硼酸盐水溶液中主要的多硼酸根阴离子及其相互作用。得到了多硼酸根阴离子的存在形式与结晶固相Cs₂B₄O₇·5H₂O和CsB₅O₈·4H₂O之间的关系。
