Front Cover: Non‐Pairwise Interactions in Parahydrogen Experiments: Nuclear Exchange of Single Protons Enables Bulk Water Hyperpolarization (ChemPhysChem 20/2018)

The Front Cover illustrates the hyperpolarization of bulk water in a recently established catalytic system. It is called NEPTUN (nuclear exchange polarization by transposing unattached nuclei) and is based on a novel non‐pairwise chemical exchange process between single p‐H2 protons and solvent molecules. More information can be found in the Communication by M. Emondts et al. on page 2614 in Issue 20, 2018 (DOI: 10.1002/cphc.201800521).
