A novel ESR based technique permitting the detection and identification of paramagnetic species, appearing in electrochemical reactions, is presented. This new method is more convenient than SEESR because it allows one to record simultaneously both the electrochemical curves and the first-order derivative curves of the ESR intensity signal depending on the applied potential, as well as to record the ESR spectra of paramagnetic radicals formed during the CV. To demonstrate the power of this method the reduction of i ndolinone-substituted methanofullerene (HBMI) has been studied. ESR spectra of paramagnetic radicals and intermediates formed during the reduction are recorded. Obtained results are used to get the complete reaction mechanism of the HBMI at the electrodes.
