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

[Offermans Willem]

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 conditions and applying a 
certain methodology. If you don’t feel comfortable with the obtained value
and you have reasonable doubts about the methodology 
or conditions (parameters), you should focus on the latter. If you need 
help with this, you should disclose the methodology and/or the 
parameters to us and discuss what you think might be wrong or 
needs reconsideration. 

I’m pretty certain that someone wants to help you out or give you advice.
With the information at hand, it will be very difficult.


Met vriendelijke groeten,
Mit freundlichen Grüßen,
With kind regards,

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 state of the Mn-atom. I have used bader charge analysis for LiMnPO4. however it doesn't give me  the oxidation state that i want.
