Cyclic voltammetry nernstian waves

Useful experimental parameters in cyclic voltammetry are (i) the value of the separation of the potentials at which the anodic and cathodic peak currents occur, A = Pia — PiC, and (ii) the half wave potential, 1/2, the potential mid-way between the peak potentials. A value of AE of c. 0.057 V at 25°C is diagnostic of a Nernstian response, such as that shown in Figure 2.87. More generally, if n electrons are transferred from R, then the separation will be 0.057/n V. It should be noted that the expected value for AE of 0.57/nV has no relationship to the usual Nernstian slope of RT/nF = 0.059/n V at 25UC.

Cyclic voltammetry (CV) scans of 5 and 6 (Fig 1) reveal two le , nearly Nernstian, oxidations. The first wave of 5 has about the same potential as does the mononuclear complex CpMn(CO)2(PPh3), If E = +0.23 V. (All potentials in this paper are referenced to Ferrocene and are collected in Table 1). The AE value for the oxidations of 5 is 210 mV. Complex 6, in which a methylene...
