In this work, pulsed-field gradients are used to modulate the radiation damping field generated by the detectioncoil in an NMR experiment in order that spins with significantly different chemical shifts can affect oneanother via the radiation damping field. Experiments performed on solutions of acetone/water and acetone/DMSO/water demonstrate that spins with chemical shift differences much greater than the effective radiationdamping field strength can still be coupled by modulating the radiation damping field. Implications forapplications in high-field NMR and for developing sensitive magnetization detectors are discussed.
