## Abstract Several methods have been established for preparing cation radicals from 1,2,4,5‐tetramethoxybenzene that allow highly resolved ESR spectra to be recorded. Precise values of the hyperfine coupling constants for the aromatic and methoxy protons have been obtained; the values are 0.2268±0
