ResumoA pulsed-field-gradient NMR experiment that permits accurate measurements of diffusion and flow rates in the presence of eddy currents is presented. The experiment employs short transverse evolution times and is thus especially useful for the study of systems exhibiting fast transverse relaxation or homonuclear scalar coupling. The insensitivity of the experiment to the presence of eddy currents is demonstrated with experiments on 5% polyacrylamide gels.
