Abstract:INEPT‐based experiments are widely used for 1H→15N transfers, but often fail when involving labile protons due to solvent exchanges. J‐based cross polarization (CP) strategies offer a more efficient alternative to perform such transfers, particularly when leveraging the Hwater
HN exchange process to boost the 1H→15N transfer process. This leveraging, however, demands the simultaneous spin‐locking of both Hwater and HN protons by a strong 1H RF field, while fulfilling the γHB1,H=γNB1,N Hartmann‐Hahn matching co… Show more
