Solution NMR spectroscopy provides rich structural information on biomolecules, however, its resolution becomes limited when molecular size increases, due to short-lived nuclear magnetic responses to electromagnetic radiation. Here, the authors sustain long-lived coherences for the aliphatic protons of glycine residues within protein lysozyme, yielding substantial through-space magnetization transfers, and mapping interacting atoms in the protein structure.
