Weband the stimulated spin-echo sequences [32], the NMR spin-echo signal intensity is sensitive to the mean square displacement r2(Δ) during the time between the pair of pulsed field gradients (t = Δ, see Fig. 2 and Eq. (2)). The spin-echo intensity M(b) is measured as function of the so-called b-value, which depends on the gradient set- WebSep 15, 2011 · Abstract. In 1950, Erwin Hahn pointed out that spin echoes in Nuclear Magnetic Resonance (NMR) could be used to measure molecular translational motion, an effect made possible because nuclear spins carry a phase determined by the history of their residence in magnetic fields.
