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 [Ti 4 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.
