Hi Oukahou & others An approach we have had some success with, depending on the possible states you are trying to distinguish, is to look at the spin density around a nucleus. That is much more sensitive to formal oxidation than the charge density. But YMMV. Ciao Terry On Tue, 2021-02-09 at

Hi Oukahou and Quantum Espresso friends, If you look for a method to give you the oxidation state you want, then I would stop looking and take the oxidation state you want. However, if a method gives you a certain oxidation state, then this is the oxidation state you obtained under certain

[QE-users] oxidation state of the Mn-atom

2021-02-09 Thread OUKAHOU SAID
Hello QE-users, I am working on lithium ion batteries specially on cathode materials. For instance, I am doing a simulation on the active material LiMnPO4, and I want to calculate the oxidation state of the Mn-atom in LiMnPO4. I would be grateful if anyone can help to figure out the oxidation
