Fred Wright said: If you isolate your experiment such that the only cause of detuning is 1/f noise, then you can take advantage of the fact that with 1/f noise there is no energy transfer to the environment. 1/f noise is reversible to some extent. Apply the pulse to the system with the spin vector aligned with the z axis of the Bloch sphere.
