Broadband magnetization transfer using moderate radio-frequency fields for NMR with very high static fields and spinning speeds

A solid-state NMR scheme dubbed PARIS-xy affords efficient low-power recoupling of dipolar interactions between nuclei such as carbon-13 over a wide range of isotropic chemical shifts. The scheme is suitable for very high magnetic fields up to 21.2 T (900 MHz) and spinning speeds up to 60 kHz.
