Resolution enhancement in heteronuclear two-dimensional spectroscopy of realignment of coherence transfer echoes

The resoln. in heteronuclear 2-dimensional NMR spectroscopy is affected by coherence transfer echoes. By introducing a delay between the transfer of coherence and the signal observation, the resoln. in the crucial w1 dimension can be enhanced. This procedure removes the symmetry of the multiplet structure, and an addnl. pulse is required to realign the signals in the 2-dimensional spectra. The methods are illustrated by applications to the indirect observation of scalar proton-proton couplings through P-31 in phosphothreonine. [on SciFinder (R)]
