摘 要: 對KPO3-MoO3熔鹽體系的拉曼光譜進(jìn)行了分析和討論，并輔以紅外光譜及31P核磁共振分析。KPO3-MoO3熔鹽體系拉曼光譜的主要貢獻(xiàn)來自于PO4四面體基團(tuán) 和MoO6八面體基團(tuán)。根據(jù)結(jié)構(gòu)與拉曼光譜的關(guān)系，推斷K(MoO2)PO4晶體的空間構(gòu)型屬Pba2 空間群。

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.
