The article presents information on heteronuclear two-bond correlation. The two-dimensional HMBC experiment stands out as one of the key NMR experiments in structure determination. HMBC spectra provide a wealth of correlations over multiple bonds and while this on one hand is desirable, it poses the problem of distinguishing particularly between two- and three-bond correlations. Conceptually, H2BC can be understood as an HMQC-COSY combination tailored to the needs of small-molecule heteronuclear NMR spectroscopy.
