“…At room temperature, the libration amplitudes are, probably, quite strong as well. This explains high temperature factors observed for Te sites, 52 which complicates the XRD analysis of LTA-Te. In contrast, this effect does not cause any trouble for polarization–orientation Raman spectroscopy, which appears to be a very fruitful method of zeolite-confined cluster study providing information on the cluster structure with distortions, orientation and interaction with zeolites.…”
