Unraveling overlapping multiplets in two-dimensional NMR spectra by selective injection of coherence

In order to sep. overlapping diagonal multiplets in two- or three-dimensional NMR spectra, new sequences using selective pulses are described which allow one to "inject" magnetization at the beginning of the evolution period by transfer from a selected coupling partner. The techniques (dubbed MUSIC, for multiplet unraveling by selective injection of coherence) can be adapted for the sepn. of overlapping cross peaks. [on SciFinder (R)]
