Using Cyclic Voltammetry to Probe Electron Transfer Mechanisms
Quick fact
In cyclic voltammetry, the separation between the anodic and cathodic peak potentials is exactly 57 mV for a fast, reversible one-electron transfer at 25 °C, but larger separations indicate slower electron transfer kinetics.
Why this is interesting
Imagine you have a molecule that either gives or take an electron. How can you tell if it does so quickly or slowly, and even measure how fast?
