英文摘要 | a series of aluminosilicate zeolites are characterized by uv raman spectroscopy for the first time, and uv raman spectra of various zeolites give strong and clear bands with high resolution, while conventional raman spectra of these zeolites are difficult to obtain because of a strong background fluorescence. additionally, these zeolites show several new bands in uv raman spectroscopy. a summary of these uv raman spectra over various zeolites suggests that the bands at 470-530, 370-430, 290-410, and 220-280 cm(-1) can be assigned to the bending modes of 4-, 5-, 6-, and 8-membered rings of aluminosilicate zeolites, respectively. furthermore, it is found that the band intensity of zeolites in uv raman spectroscopy is dependent on the si/al ratio. moreover, the uv raman spectra of crystallization, for zeolite x at various times show that, in the initial stage of crystallization, the 4-membered rings (510 cm(-1)) interconnect each other to form beta -cages with 6-membered rings (390 cm(-1)), which further crystallize to zeolite x.
