The electrochemical reduction of 3-nitro-benzoic acid (3-NBA) has been investi-gated on Pt electrode in DMSO media by cyclic voltammetry and controlled potential electrolysis, in combination with ESR spectroscopy. The results show that 3-nitro-ben-zoic acid is reduced through a three-electron process to a of species of nitroso group. Hyperfine structures of ESR spectrum of the free radical were observed. The ESR parameters of the simulation have been determined as a_1~N = 10.91G, a_2~H=1.12G, a_4~H=a_6~H=3.38G, a_5~H=3.96G. The rate constant of the decay of free radical was evaluated as k=k=4.814×10~(-2)s~(-1).
