New data acquisition and data processing strategies are combined to give enhanced 2D HSQC spectra. Complete carbon-13 assignments can be obtained using only two proton spectra in some cases. A composite pulsed Ðeld gradient is employed which appears e †ectively instantaneous, as far as spin evolutio
