✦ Synopsis

Selective 1 H-13 C inverse NMR experiments based on heteronuclear cross-polarization (HCP) are presented. Practical details on the implementation of one-bond [ 1 J C,H ] optimized and pseudo-3D HCP experiments combined with gradient coherence selection are reported. On the other hand, accurate values for long-range proton-carbon coupling constants [ n J C,H ; n > 1] can be measured from ultra-clean in-phase 1D proton multiplets resulting of long-range optimized experiments. Alternatively, such heteronuclear connectivities can be also clearly elucidated using a 1 H-selective 13 C-detected version in which signals exclusively arise from selective transfer of a selected proton to all long-range coupled carbon nuclei.
