We have performed measurements and numerical reconstruction of the temperature dependence of the EPR spectrum of the 2-nitro-1,4-bis(trifluoromethyl)benzene radical anion in anhydrous acetonitrile, caused by dynamic modulation of the fluorine isotropic hyperfine interaction by hindered internal rotation of the CF3 group ortho to the nitro group. The activation energy of rotation is 34.2 +/- 0.76 kJ.mol(-1).
