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.
There are 2 explanations – (a) multiple shake-ups versus (b) super coster kroning
