AbstractA two‐dimensional (2D) NMR spectrum is produced from the double Fourier Transform (FT) of two time domains,t1andt2. One of these domains,t2, is identical to the acquisition time used to collect a Free Induction Decay (FID) in one‐dimensional (1D) NMR spectroscopy. After performing the FTs of a series of these FIDs, an array of resonance lines is obtained whose amplitudes and phases are a function oft1. Thet1domain is then composed of another series of “FIDs” that are related to those collected duringt2. In this article, it is shown that in a heteronuclear‐J, δ gated‐decoupling experiment, the “FIDs” in thet1domain produce, after the FT, proton‐coupled spectra whose sum is identical to that obtained from a 1D carbon FID collected with no
