Koster-Kronig Effect or Multiple Shake-ups in
Ti (2p1) in TiO2
Super Coster-Kronig Effect or Multiple Shake-ups for Ti (2p1) in TiO2
| Here is an overlay of the Ti (2p) signals from pure Ti metal and a single crystal of TiO2.After removing the chemical shift effect from TiO2, and making an overlay, we can see that the Ti (2p1) signal for TiO2 is ~0. 3-0.4 eV lower than the Ti (2p1) from Ti metal.
Why? There are 2 explanations – (a) multiple shake-ups versus (b) super coster kroning |
