The universality of using refocusing pulses to improve existing standard decoupling sequences is probed. The success of this approach relies on judiciously choosing the phase of the π pulses.

Decoupling requires careful pulse parameter optimization which is tedious and practically impossible for insensitive samples. Can we make it parameter independent? Yes. The solution is provided in this paper for fast MAS regime.
