A new solid-state NMR technique for recoupling heteronuclear dipolar interactions under magic angle spinning is proposed. In this method, the recoupling is achieved by interference between two non-commutable time-dependent Hamiltonians in the doubly rotating frame: one is the heteronuclear dipolar i

The maximum of the transferred magnetization in rotating powdered solids under the radiofrequency-driven recoupling (RFDR) pulse sequence is enhanced by reducing the orientation dependence of the effective recoupled homonuclear dipolar interaction. The compound RFDR (CRFDR) pulse sequence for this e
The rate constant of radiofrequency-driven (RF-driven) polarization transfer and that of polarization transfer under slow-magic-angle sample spinning (S-MAS) are compared using a model system, polycrystalline alpha-alpha'-13C2-phthalic acid. While the rate constant under RF irradiation in static sam
