Charge transfer in Ti–zeolites : Model titanium–zeolites containing a single Ti( IV ) tetrahedral species were built and their electronic excitation spectra were calculated (see picture) via time‐dependent density functional theory (TDDFT). A multiple‐band profile was obtained in each case, thus highlighting that the features observed in the UV/Vis spectra are not a direct evidence of chemically different Ti( IV ) sites.
