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

A new two-dimensional pulse sequence for accurately determining heteronuclear coupling constants is presented. It is derived from HSQC and HECADE techniques with B 0 gradient coherence selection. The main feature of the proposed method is spectra with only one component of the IS doublet; i.e., the
## Abstract A modified version of CPMGβHSQMBC pulse scheme is presented for the measurement of longβrange heteronuclear coupling constants. The method implements adiabatic inversion and refocusing pulses on the heteronucleus. Lowβpower composite 180Β° XYβ16 CPMG pulse train is applied on both proton
