The proof of the pudding is in the analysis! The mononuclearity of the metal in a zeolite‐supported Rh + catalyst with two exchangeable ethylene ligands (see picture; Rh brown, C black, Al gray, O red, Si blue) was confirmed through EXAFS studies, and its dynamic uniformity was demonstrated through variable‐temperature NMR spectroscopic studies.
