DISCRETE MAGNETIZATION GRATINGS IN NMR-SPECTROSCOPY

A new class of pathway-selective high-resolution gradient NMR experime nts is introduced, in which the spatial evolution due to the magnetic field gradient is employed to discretely spatially modulate the pulse sequence as seen by the spins. For multiple quantum filtered experimen ts this approach retains the full sensitivity of the phase-cycled anal ogs while at the same time benefiting from the gradients increased dyn amic range and reduced experiment times.
