|a Heteronuclear one-bond couplings have a variety of applications, and their accurate determination is the basis for obtaining specific structural information of mostly small organic compounds. In this context, it is of utmost importance to reduce signal overlap to a minimum, and a number of techniques has been introduced during the last decades. Here, we introduce a modified version of the HR-HMBC (Magn. Reson. Chem. 2010, 48, 179-183) for heteronuclear one-bond coupling measurements with improved resolution because of the J-resolved-like tilt of corresponding multiplet patterns. The pulse sequence is introduced, and its performance is compared with a standard ω(2)-coupled HSQC experiment. Example spectra on glucose and maltose demonstrate that signals can be resolved that overlap otherwise. The approach is discussed in detail
