Although scalar-coupling provides important structural information, the resulting signal
splittings significantly reduce the resolution of NMR spectra. Limited resolution is a particular …

Recently, we have shown that net magnetization transfer among scalar coupled
homonuclear spins can be obtained by the application of a spin-lock field (I), or more …
