Quantitative EPR spectroscopy of 0.82 mM diradical dication 12•2+ 2SbF6 in DBP: experimental values of χT (mean ± SE, n = 3), the product of paramagnetic susceptibility (χ) and T in the T = 105 – 330 K range and numerical one-parameter fit with the variable parameter, 2J/k = 145 ± 4 K (mean ± SE). Further details are reported in the SI, Fig. S12, S16, and S26.
