WebApr 10, 2024 · In computational electrochemistry and electrocatalysis, DFT is most often used for computing (free) energy differences related to adsorption, reaction thermodynamics, or kinetics. We will focus on how the electrochemical conditions, i.e., the electrolyte and the electrode potential, influence these energetic differences. The discrete Fourier transform is an invertible, linear transformation $${\displaystyle {\mathcal {F}}\colon \mathbb {C} ^{N}\to \mathbb {C} ^{N}}$$ with $${\displaystyle \mathbb {C} }$$ denoting the set of complex numbers. Its inverse is known as Inverse Discrete Fourier Transform (IDFT). In other words, for any … See more In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), … See more Eq.1 can also be evaluated outside the domain $${\displaystyle k\in [0,N-1]}$$, and that extended sequence is $${\displaystyle N}$$-periodic. Accordingly, other sequences of $${\displaystyle N}$$ indices are sometimes used, … See more The ordinary DFT transforms a one-dimensional sequence or array $${\displaystyle x_{n}}$$ that is a function of exactly one … See more The DFT has seen wide usage across a large number of fields; we only sketch a few examples below (see also the references at the end).
