Getting the Most Out of HSQC and HMBC Spectra - ScienceDirect

WebHMBC spectra provide a wealth of correlations over multiple bonds, and while this on one hand is highly attractive, it poses the problem of distinguishing particularly between two- and three-bond correlations. Several methods have been proposed to this end, and will be briefly exposed in the following. [Pg.324] WebIn the StrucEluc software system the common lengths of the connectivities, 1-bond for COSY and 1- or 2-bond for HMBC, derived from 2D NMR data are set as the default. Therefore, in the presence of any extended connectivities contradictions can appear in the 2D NMR data.
