Magnetic field gradients were incorporated into the selective COSY experiment. The new gradient‐selected experiment has the expected advantages of significantly improved spectral quality resulting from better artifact suppression and the capacity to acquire spectra using fewer scans. A sample of brucine was used to evaluate the experiment and the resulting spectra were of excellent quality. These experiments may be implemented on commercial instrumentation.
