Uncompensated solution resistance in NPSV

The current—potential curve in the region where varies from 0.20 to 0.80 is the most useful for NPSV analysis. When the data are divided into two overlapping segments, /N = 0.20 to 0.50 and /N = 0.50 to 0.80, the 

NPSV slopes for the two segments, mj and m2, will be identical when Ru is zero, but will differ when this is not the case [46]. Thus, the Rt feedback circuit of the potentiostat can be fine-tuned so that mj is equal to m2 and, under these conditions, Rf is equal to Rf. The original literature [46] should be consulted for details of the method. 

The applications of LSV and CV are so numerous that any attemps to review this area is far beyond the scope of this chapter. Instead, a limited number of applications are described which demonstrate the qualitative use of CV, application of both CV and LSV to the study of heterogeneous charge transfer, and the application of both techniques in the study of the kinetics and mechanisms of homogeneous reactions coupled to charge transfer. The examples chosen are from my own work. This is simply a matter of convenience and familiarity rather than a reflection of the importance of the particular studies. 

1 THE REACTIONS OF IONS GENERATED FROM 9,10-DIARYL-ANTHRACENES IN SOLVENTS OF LOW NUCLEOPHILICITY 

Cyclic voltammetry is a very valuable tool to use in following the course of redox reactions. An instructive demonstration of this is provided by studies on the oxidation of 9,10-diarylanthracenes in CH2C12—CF3C02H which can be considered to be nucleophile poor [81]. The use of CV in these studies is exemplified by Fig. 6. The first voltammogram [Fig. 16(a)] was recorded before bulk electrolysis was started. Peaks Ot and 02 correspond to the 1 e oxidations of 9,10-diphenyl-anthracene (DPA) and
