摘 要: 研究 了CoNaY，NiNaY，CdNaY，CaNaY及晶体结构已被破坏的“CrNaY"，在523 K 和10-1Pa条件下处理后及其吸附苯后的红外光谱，认为415 cm-1谱带归属于六元环的振动，403cm-1 归属于十二元环的振动，511 cm-1 吸收谱带归属于Si—O1—T的弯曲振动。 \解释了Y型分子筛的Si—O1—T易于断裂及511cm-1谱带频率大于462cm-1谱带频率的原因。

Abstract:To detail assignment of Y-type zeolite framework IR vibrational bands, CoNaY, NdNaY and CrNaY with demolished structure were treated at the conditions of 523K, 10-1Pa and adsorbed benzene molecules, then their IR spectra were investigated. It is suggested that the band at 415cm-1 is assigned to vibration of 6R , the band at 403cm-1 is assigned to vibration of 12R and the band at 511cm-1 is assigned to bending vibration of Si—O1—T. The reasons of Si—O1—T is subject to be broken and the band at 511 cm-1 is situated higher frequence than the band at 462 cm-1 have been explained.
