Abstract
Migrating spins subjected to a nonuniform radiofrequency field bring about an unusual magnetic resonance response. The article shows that the observed [1], NMR linewidth broadening in the inhomogeneous rf field, interpreted in previous publications as due to a shortening of the relaxation time, can also be understood in terms of movement of nonuniformly excited spins across the receiving coils. Results for the self-diffusion and the liquid flow are presented
