The suggested approach is based on the efficiency in refocusing the proton … WebFor investigating chain dynamics in the PE samples, we used the magic sandwich echo (MSE) sequence, as shown in Figure 2. It refocuses the rapidly decaying signal after a 90° pulse which is governed by strong 1 H dipole–dipole interactions. The echo produced by the sequence appears after a distinct time after the last pulse.
