Figure 1
The mid-IR spectrum between 389 and 1300 cm-1 of SU-66 compared with selected germanates built from various clusters. The IR spectrum of SU-66, with bands corresponding to Ge-O vibrational modes, shows a close resemblance to that of ASU-21, a phase built from Ge10 clusters only.  [article HTML]
