Fourier‐transformed large‐amplitude AC voltammetry (FTACV) as utilized by A. M. Bond, J. Zhang et al. on p. 99 provides a powerful tool for quantitative electrode kinetic studies. In this context, the method has exceedingly high sensitivity compared to DC voltammetry and conventional small‐amplitude AC voltammetry and all data needed are derived from a single experiment. In FTACV, a large‐amplitude AC perturbation is superimposed onto the DC ramp. The total current response is then resolved into DC and AC harmonic components using the FT/inverse‐FT protocols. Kinetic and mechanistic information can be obtained conveniently from the background‐free higher harmonic components present when a large‐amplitude AC perturbation is employed. Valuable information is also derived from the DC and fundamental harmonic component. The cover picture demonstrates the application of FTACV for the measurements of the kinetics of fast electron transfer processes associated with tetrathiafulvalene.
