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
In this work we present a new pulse sequence for the measurement of long-range heteronuclear coupling constants in which the optimization of coherence selection by pulsed field gradients offers a net increase in sensitivity. This type of experiments is extremely valuable for conformational studies o
