Slow hindered rotation of CF3 group in radical anion of ortho nitrobenzotrifluoride in N,N′-dimethylformamide and reconstruction of EPR spectrum

The temperature dependence of the EPR spectrum of the 2-CF3-C6H4-NO*2 radical anion in anhydrous N,N′-dimethylformamide, caused by hindered internal rotation of the CF3 group with an extreme activation energy of 34700 J·mol-1, was experimentally studied and reconstructed. © 2007 by Allerton Press, Inc.
