carbon‐substituted aziridines. The origin of these is identified as scalar cross‐relaxation of the first kind, as demonstrated by a complete theoretical description of this relaxation process and by computational simulation of the NOESY spectra. It is shown that this process relies on the stochastic modulation of J‐coupling by conformational transitions, which in the case of aziridines arise from inversion at the
