Hi, Professor Marks:

The following is the results from the label of :NEC:

About the charged state of defects in diamond, transitions among different 
charged states are possible to show up depending on the location of the Fermi 
energy. You can think about the nitrogen vacancy center, which has two stable 
states, i.e. neutral and -1 charged. The latter is proved to exhibit a spin one 
ground state.  Even though the supercell calculations have some flaws, my 
calculations so far qualitatively show a similar result in some charged 
isolated vacancy depending on various factors. The charged electron should be 
delocalized, but I can’t confirm the extent without a converged results. The 
thing I can confirm is that the magnetic moment are all from the defect level. 
Or maybe I didn’t get your question very well. If any other information about 
my calculation is needed, please let me know.

Thank you very much for your help. I really appreciate it.

Wenhao
