12-P-10 - Raman study of the building units in the zeolite structure

Publisher Summary This chapter discusses the Raman study of the building units in the zeolite structure. The Raman effect is an intrinsically weak phenomenon, and Raman spectra of zeolites are often obscured by a broad fluorescence. Just as infrared (IR) spectroscopy, Raman can detect small, X-ray amorphous zeolite particles. Therefore, Raman spectroscopy has been used to examine zeolite synthesis mixtures with ex-situ methods (with separation of solid and liquid) and in situ methods. The chapter also provides an overview of the zeolite framework vibrations, zeolite synthesis, adsorption on zeolites, and metal substitution and ion exchange in zeolites.
