Abstract
Raman spectroscopic investigations reveal the synthesis of Ti-Silicali te I with four-fold coordinated titanium. A new Raman band at 960 cm-1 assigned to tetrahedrally coordinated titanium in the SiO2 matrix is found. Non-framework TiO2 species containing octahedrally coordinated titanium could be also distinguished.
