报道了钡钛锗（Ba 2 Ti（Si，Ge）2 O 8）玻璃的拉曼光谱，并对Ba 2 TiSi 2 O 8和Ba 2 TiGe 2 O 8的相应晶体粉末和玻璃的拉曼光谱进行了比较. Ba 2 TiGe 2 O 8玻璃的光谱与Ba 2 TiGe 2 O 8晶体的拉曼光谱相一致，玻璃中的Raman（Ge-O-Gea）模位于518 cm-1，晶体中的Raman（Ge-O-Gea）模位于521 cm-1
Raman spectra are reported for fresnoite (Ba 2 Ti(Si, Ge) 2 O 8 glasses, and comparison is made between the Raman spectra of the corresponding crystalline powders and glassess of Ba 2 TiSi 2 O 8 and Ba 2 TiGe 2 O 8 . The Ba 2 TiGe 2 O 8 glass spectra show correspondence with the Ba 2 TiGe 2 O 8 crystalline Raman spectra; the υ s (Ge-O-Gea mode occurs at 518 cm -1 in the glass and at 521 cm -1 in the crystalline material
