The Fe2S2 complex derived from the 20-peptide exhibits a visible spectrum typical of plant-type 2-Fe proteins (10). (See Figure 4.) But at least two isomeric 2-Fe species are detect by the cyclic voltammetry (CV) and also by the differential-pulse polarography in DMF. One isomer has an E1/2 at -0.64 V (SCE), which is very similar to that of the native protein, and this complex presumably adopts a structure... 

An enantiopure dimer 149 with a l,l -binaphthyl-bridge was prepared via the bis-tosylhydrazone (see Table 4.4, page 130/131) [122], The electronic properties of these dimers, such as the electronic absorphon spectra and cyclic voltammetry, are indistinguishable from those of other methano-bridged fullerenes. CV-data show clearly that the two CgQ-imits of the binaphthyl-dimer are reduced independently [122],... 

As mentioned above, the characteristic feature of processes in this kinetic region is that the peak current ratio — z°x/Zped varies from about unity to zero. Thus, a procedure for studying the kinetics would be to record values of —/°x//ped at different sweep rates and compare these with a working curve for the proposed mechanism in a way analogous to that discussed for DPSCA above. However, a problem with this approach is the difficulty of defining a baseline for the reverse sweep (see below) and, for that reason, CV suffers from some limitations when used in quantitative work. This has led to the development of derivative cyclic voltammetry (DCV) [37]. 

If the potential is inverted at a given value (inversion or final potential) until the initial potential is reached again, the two above techniques are denoted Cyclic Staircase Voltammetry (CSCV) and Cyclic Voltammetry (CV), respectively (see Scheme 5.3). The potential waveform in CV can be written as a continuous function of time... 

One of the main uses of digital simulation - for some workers, the only application - is for linear sweep (LSV) or cyclic voltammetry (CV). This is more demanding than simulation of step methods, for which the simulation usually spans one observation time unit, whereas in LSV or CV, the characteristic time r used to normalise time with is the time taken to sweep through one dimensionless potential unit (see Sect. 2.4.3) and typically, a sweep traverses around 24 of these units and a cyclic voltammogram twice that many. Thus, the explicit method is not very suitable, requiring rather many steps per unit, but will serve as a simple introduction. Also, the groundwork for the handling of boundary conditions for multispecies simulations is laid here. 

Formal potentials are frequently reported from cyclic-voltammetry (CV) measurements. If the system is reversible or quasireversible, the average of Ep and E [see Eq. (d) in 12.3.2.1.4] is used to compute E for the couple. However, unless the couple is reversible this procedure can lead to errors. For the cyclic scan in Fig. 1, two possible mechanistic interpretations can be considered. One is for a quasireversible couple ... 

Bulk electrolyses are used to prepare one-electron reduction or oxidation products. If cyclic voltammetry (CV) reveals reversible redox, the bulk preparation of the reduced (or oxidized) product may be attained. The overall electrode process may be different in controlled-potential electrolysis and in CV because of the time factor (see below). The iron cluster, (h -CjHjFeCO), in nonaqueous electrolytes undergoes a four-membered electron-transfer CV series through three steps. The potentials measured (in CHjCN/O.l M [n-Bu N] [PFJ) are ...

The first group consists of conventional electroanalytical techniques such as cyclic voltammetry (CV), chronoamperometry, chronopotentiometry, coulometry, and electrochemical impedance spectroscopy (EIS), all of which provide general information about the doping process (see also Chapters 4 and 5). Below are listed some typical questions that can be answered using the above group of techniques ...
