  • E1/2 is used in techniques providing a sigmoidal wave-shaped current including DC voltammetry/polarography, normal pulse voltammetry, hydrodynamic voltammetry, and tast polarography. [en]
  • For quasi-reversible and irreversible electrode reactions, the value of E1/2 is also affected by the rate constant of the charge transfer reaction, the difference being greater than that caused by different diffusion coefficients. [en]
  • The quarter-wave potential, Ep/4, the three-quarter-wave potential, Ep3/4 , etc., may be similarly defined. [en]
