A simple pulse sequence in inverse-detection mode is proposed for the detection of heteronuclear long-range couplings. In the resulting 2D heteronuclear multiple-bond correlation (HMBC) spectra, pure-absorptive peak patterns are obtained along both frequency dimensions. Since the heteronuclear coupl
Long-range heteronuclear coupling constants, n J XH , have been recognized as an important source of information in the structural elucidation of molecules (1). Accordingly, a large number of methods for their measurement have been proposed to date . Often these methods rely on the characteristic sp
