Dft indices
WebNov 30, 2016 · In this Special Issue, several studies in which the analysis of the DFT reactivity indices of the reagents involved in organic reactions provides meaningful information are presented, thus reflecting the broad … 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). All applications of the DFT depend crucially on the availability of a fast algorithm to compute discrete Fourier transforms and their inverses, a fast Fourier transform. When the DFT is used for signal spectral analysis, the sequence usually repres…
