WebThe U.S. Department of Energy's Office of Scientific and Technical Information WebOne problem associated with measuring a free induction decay (FID) is that, due to the T2∗ relaxation, its amplitude rapidly decreases. To mitigate this, a second RF pulse is often employed to rotate the rapidly dephasing proton spins by 180 degrees. The pulse sequence for this protocol, shown in Fig. 7.14, creates an echo with a much better signal-to-noise …
