WebSpin echo for (homonuclear) coupled spins I a spin echo is equivalent to 1.evolution of the coupling for time 2˝ 2.followed by a 180 pulse (here about x). Ithis is a very useful short cut in calculations I key thing about a spin echo is that it enables us to interconvert in-phase and anti-phase magnetization in a way which is 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-
