摘 要: 对KPO3-MoO3熔盐体系的拉曼光谱进行了分析和讨论，并辅以红外光谱及31P核磁共振分析。KPO3-MoO3熔盐体系拉曼光谱的主要贡献来自于PO4四面体基团 和MoO6八面体基团。根据结构与拉曼光谱的关系，推断K(MoO2)PO4晶体的空间构型属Pba2 空间群。

Abstract:The Raman spectra of KPO3-MoO3 molten salts binary system was studied with supplimentary IR and 31P NMR data. The results showed that the PO4 tetrahedrons and MoO6 octa-hedrons play important roles in Raman spectra of KPO3-MoO3 molten salts system. The space group of K(MoO2)PO4 crystal is inferred to be Pba2 according to the relationship of crystal structure and Raman spectra.
Key words: KPO3 MoO3 K(MoO2)PO4 Raman spectra crystal structure
