The most rigorous way is always calculating and comparing free energy energy barriers of various possible O2 formation reactions, while dual descriptor analysis may be used to explain the difference.

I calculated the dual descriptor for all of them. Some of them are nucleophiles and some are electrophile. How to decide which oxygen will participate in the reaction? May I compare to a different molecule in which I know the value of the dual descriptor of reactive oxygens?
(Of course I could compare them to each other but the problem is that I have more than one model and in one model there is a more reactive oxygen that the other one but the 2 models have a very similar energies).
Thank you
