Fast adiabatic pulses for solid-state NMR of paramagnetic systems

We demonstrate the use of short, high-power adiabatic pulses (SHAPs) for population inversion in paramagnetic solids, and show its application in refocusing schemes and TEDOR NMR experiments for various systems with differing proton anisotropies in iron, ytterbium, and terbium complexes, from 400 to more than 1000 ppm.
