摘 要:   研究了CrNaY(晶体结构已经破坏)及CoNaY, NiNaY, CNaY 和CaNaY的红外光谱,认为:1 150 ~ 1 050cm-1和850~750 cm-1 分别归属于Si—O—T的反对称和对称伸缩振动,同时发现: CoNaY, NiNaY, CdNaY和CaNaY在真空加热处理后, CoNaY和NiNaY在950~850cm-1 范围内出现吸收峰。

Abstract:The spectra of CrNaY(which has demolished), CoNaY, NiNaY, CdNaY and CaNaY were investigated. It is suggested that the bands in the rangeof 1 150~1  050  cm-1 and 850~750  cm-1 are assigned to the asymmetric and the symmetric stretching vibration of Si—O—T respectively. It is discovered that the absorption peak arises in the range of 950~850  cm-1 in CoNaY and CaNaYrespectively after CoNaY, NiNaY, CdNaY and CaNaY were heat treated under vacuum.
