The use of both proton and deuterium dipolar coupling networks to obtain efficient C-13 magic-angte-spinning NMR correlation spectroscopy is introduced. This new strategy aims to improve the efficiency of C-13 spin diffusion in perdeuterated proteins. The method is called doubte-nucleus enhanced recoupting (DONER), and it provides significantly improved transfer efficiency for carbon spin diffusion at low proton density. The C-a cross-peak intensity in the DONER experiment is similar to 3 and similar to 5 times stronger than those in conventional radio-frequency-assisted diffusion (RAD) and proton-driven spin diffusion (PDSD) experiments, respectively. Remarkably, the full cross-peak pattern for the aliphatic region of an extensively perdeuterated SH3 protein sample can be obtained using the DONER approach with direct C-13 excitation.
