Corrigendum: Reply To: How Does Substitutional Doping Affect Visible Light Absorption in a Series of Homodisperse Ti11 Polyoxotitanate Nanoparticles-A Comment on the Band Gap Determination of the Fe(II) Cages.

A summary of the evidence based on spectroscopy, calculated density of states (DOS) and photo-electrochemistry, for electron transfer from the occupied Fe(2+) (d)-β orbital located within the band gap of the [Ti4 O(OEt)15 (FeBr)] cluster, to its unoccupied Ti(d) orbitals is presented. The importance of the distinction between the concepts of band gap and HOMO-LUMO gap is emphasized.
