2. In the recent paper of professor cho's group, [JACS,2017], they showed EPR spectra of [Co(II)(TBDAP)(H2O)(NO3)](NO3) in a range of 25 mT to 35 mT (here, they used acetonitrile as a solvent). I think, it would be better for comparison to measure the spectrum in a wider range but I am not sure about this. 
3. At our last meeting, Professor Lim and you expected  [Co(II)(TBDAP)(H2O)(NO3)](NO3) in basic solvent with aerobic condition (750 nm peak distinctively growing) as Co(III) superoxo species. Regarding this, should I measure EPR specrum in parallel mode as well as perpendicular mode?Now that this is my very first time to maesure EPR sample, I was afraid that I would not be able to determine the experimental condition properly. Thank you very much for your time.
