    • We obtain good fits to a biexponential decay function which accounts well for the two emitting regions in this system. Closer analysis is likely to reveal that the decay is more complex and better fit to a distribution function, as is well-known in heterogeneous porous media. [For a lucid discussion of decays in heterogeneous porous solids see: Castellano, F.; Meyer, G. J. In Progress in Inorganic Chemistry; Karlin, K. D., Ed.; Wiley: New York, 1997; Vol. 44, p 167 and references therein.]

    • note
    • Lamnberti et al. [ref 13] also report an emission centered at 500 nm for the tetrehedral model compound Ti(OSi(CHj)3)4. This observation was used to assign the low-energy band as originating from a tetrahedral site in the lattice. We observed no emission from this compound either in . cyclohexane at room temperature or in a methylcyclohexane glass at 77 K.

    • g = ve [Yersin, H.; Otto, H.; Zink, J. I.; Gliemann, G. J. Am. Chem. Soc. 1980, 702, 951]; however, given the complexity of the spectra and the qualitative nature of this Franck-Condon analysis, this higher level of calculation seems unwarranted.

    • While this value of the optical electronegativity for the oxo ligand is probably reasonable, it should be noted that there are a number of problems in assigning optical electronegativites for oxygen [Muller, A.; Diemann, E.; Jørgensen, C. K. Struct. Bonding 1973, 14, 23].
