Efficient heteronuclear dipolar decoupling in solid-state nuclear magnetic resonance at rotary resonance conditions

We introduce here a heteronuclear dipolar decoupling scheme in solid-state nuclear magnetic resonance that performs efficiently at the rotary resonance conditions, where otherwise dipolar couplings are re-introduced. Results are shown proving the efficiency of this scheme at two magnetic fields under magic-angle spinning frequencies of 30 and 20 kHz.
