Low-power broadband homonuclear dipolar recoupling without decoupling: Double-quantum 13C NMR correlations at very fast magic-angle spinning

► New series of homonuclear 2Q recoupling sequences for fast-MAS NMR operation. ► Each pulse-sequence member is generated recursively and requires very low rf power. ► A high-order average Hamiltonian analysis predicts progressively improved resonance-offset compensation. ► The theoretical predictions are verified experimentally and numerically. ► A 2Q-1Q correlation NMR experiment is demonstrated on [U-13C]tyrosine.
