Notes:
Several recent papers have dealt with the modulation of protonated carbon response intensities in long-range heteronuclear 2D NMR chemical shift correlation spectra. Expressions describing the one-bond modulation of the response intensity of the C-3 methylene resonance of 6,7-dimethoxy-3,4-dihydroisoquinoline, and the decoupling of this modulation afforded by a BIRD pulse located midway through the Δ2 refocusing delay, are presented with experimental confirmation. Long-range response intensities are related to the conventional heteronuclear chemical shift correlation spectrum optimized for transfer from the directly attached proton.
