Abstract

We report the application of a dipolar recoupling sequence for the observation of ¹³C–¹³C connectivities in biomolecules at high magnetic fields (B₀ ≥ 21.1 T) and ultra-high magic angle spinning frequencies (ν_R = 60 kHz). The efficiency and the robustness of this double-quantum technique are demonstrated on the YajG protein (19.6 kDa).
