Brønsted acidic sites on catalyst surfaces are observed by 17 O dynamic nuclear‐polarization‐enhanced NMR spectroscopy, which hyperpolarizes nuclei by microwave‐induced saturation of electrons. In their Communication on page 9165 ff., M. Pruski et al. report the measurement of O−H distances with sub‐picometer precision. The length of the O−H bond is directly related to the Brønsted acidity of the sites and is also a reporter of the formation of intermolecular hydrogen‐bonding interactions.
