Spin Echoes

The decay of the primary spin echo due to diffusion is governed by the expression [Formula: see text]. This statement is independent of the angles through which the magnetization is rotated by the radio frequency (r-f.) pulses. For the usual range of experimental values, it is also independent of the intensity or homogeneity of the r-f. field, the duration of the r-f. pulse, and the magnitude of the constant field gradient.

3-Azido-1-propyne oligomer (oligoAP) samples, prepared by copper(I)-catalyzed azide–alkyne cycloaddition (CuAAC) polymerization, were quarternized quantitatively with methyl iodide in sulfolane at 60 °C to obtain soluble oligomers. The conformation of the quarternized oligoAP in dilute DMSO-d 6 solution was examined by pulse-field-gradient spin-echo NMR based on the touched bead model.
