galvinoxyl	toluene	2.0044	250
N@C₆₀	CCl₄	2.0022*	48
N@C₆₀	CHCl₃	2.0022*	48
TEMPONE-¹⁵N-d₁₆	toluene	2.0059	447
TEMPONE-¹⁵N-d₁₆	CCl₄	2.0062	486
TEMPONE-¹⁵N-d₁₆	CHCl₃	2.0060	461

Isotropic g-values of various PAs in selected solvents corresponding resonance frequency shifts $Δ ν$ with respect to that of BDPA in toluene at 9.4 T. The g-reference radicals⁵³ in the corresponding solvents are indicated by an asterisk. N@C₆₀ was calibrated in-house to a carbon fiber⁵². Precision of g_iso is 50 ppm. Data shown in Fig. 1c and Supplementary Fig. 17. Source data are provided as a Source Data file⁶⁰.
