摘要：
The characteristic yellow color of the TS-1/H2O2/H2O system is attributed to a "side-on" Ti-peroxo species, presumed to be the active intermediate in partial oxidation reactions. Resonance Raman spectroscopic analysis of both the zeolite system and a model salt ((NH4+)3 (TiO2F5)3-, see picture) are combined with the analysis of a Ti-free silicalite to prove the structure of the hitherto unknown species.
