Dear all, I am still a begeinner who has used QE for few years. I have read the paper about oxidation state constrained DFT (i.e. oscdft) from this link Oxidation-State Constrained Density Functional Theory for the Study of Electron-Transfer Reactions | Journal of Chemical Theory and Computation<https://pubs.acs.org/doi/10.1021/acs.jctc.9b00281>.
The description and results are quite comfusing to me: "First, we performed DFT calculations on the Fe2+(H2O)6 cluster and the Fe3+(H2O)6 cluster as shown in Figure S1. The occupation numbers are shown in Table S1. The target values are therefore 0.94 for the Fe2+ ion and 0.26 for the Fe3+ ion applied to the spin down 5th occupation number." So, 1. How to set Fe2+ and Fe3+ to run pw.x? 2. How to get the occupation numbers and target values from the results? Can you provide more detail and workflow of running oscdft? Mnay thanks!
