Fast 1D long-range proton-proton correlations

“Selective 1D HCH experiment: a fast NMR tool that connect protons belonging to different spin systems”, by Sergi Gil, Juan Félix Espinosa and Teodor Parella; Magnetic Resonance in Chemistry 49, 301-306 (2011). DOI: 10.1002/mrc.2744

A selective 1D version of the HCH experiment (selHCH) is proposed for the efficient and fast correlation between protons belonging to different spin systems. The experiment consists of two consecutive, doubly selective heteronuclear JCH transfer steps that can individually be optimized. As any conventional proton-selective 1D experiment, the successful application of a frequency-selective 180° pulse on a well-isolated proton is the only practical requirement.
