The known 1 H NMR chemical shifts of diamagnetic compounds so far range from around δ =−60 ppm to about +20 ppm. In their Communication on page 10884 ff., P. Hrobarik, M. Kaupp, et al. predict that, because of giant relativistic spin‐orbit effects, the 1 H NMR shifts of the to‐date elusive uranium(VI) hydride complexes will be between δ =+40 ppm and more than +150 ppm, a completely unprecedented range. Knowing the correct spectral range to look for should facilitate the characterization of this new compound class.
