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.
