a EDFS and field-sweep 2D nutation spectra with the Zeeman energy level diagram (assuming D > 0); b electron spin nutation and Fourier transformation profiles at 9 dB power decay; c nutation frequency data (with fitting) showing linear dependence on the varied microwave field (B1), exhibiting slope ratios (2:√3) characteristic of S = 3/2 species; all experiments are conducted in frozen toluene-d8 at 20 K.
