摘要：

A new solid-state MAS NMR experiment is described that recovers the dipolar interaction between spin-1/2 nuclei and quadrupolar nuclei spin pairs. This technique combines the principles of rotational-echo, double-resonance (REDOR) NMR and transfer-of-populations-double-resonance (TRAPDOR) NMR. Dipolar evolution is driven by a REDOR-like pi-pulse train applied to the spin-1/2 nuclei and by a single TRAPDOR-like adiabatic-passage pulse applied to the quadrupolar nuclei.
