Electronic spin structure of 2. a Observed and simulated hyperfine electron paramagnetic resonance (EPR) spectra of 2 in toluene (1 × 10–4 M) at 293 K. b Temperature dependence of the EPR intensity of 2 in toluene (8 × 10–5 M), where plot and solid line denote the experimental values normalized at 370 K and the calculated value. c Observed (black) and calculated (red) hfcc values of 2. d Calculated spin-density distribution of 2. Red and blue regions denote positive and negative spin densities, respectively
