Can you observe an "intermediate" oxidation state in a non-stoichiometric oxide by XPS/ESCA?

Hello, I am having a debate with some colleagues about how we believe a non-stoichiometric oxide would be observed in XPS. Let's say we have an oxide in the form of AB2-x (A = transition metal,...

Hello, In XPS measurements, I am observing consistent shifts in spin-orbit splitting values for different oxides of the same base element. I'm being told by many that this is not possible, that...
