Suppression of artifacts in two-dimensional J spectroscopy
Spurious responses, known as phantom and ghost responses, in NMR 2-dimensional J spectroscopy, can be removed by a 4-step sequence where the phase of the C refocusing pulse is cycled through O, 90, 180, 270 Deg while the receiver ref. phase is alternated. This phase-cycling sequence was applied to the 2-dimensional J spectrum of 13C in MeOH obtained by the proton flip technique; both the phantom and ghost multiplets were canceled. [on SciFinder (R)]
