HIGH-RESOLUTION NMR EXPERIMENTS WHICH USE FREQUENCY-SELECTIVE RF PULSES IN COMBINATION WITH MAGNETIC-FIELD GRADIENTS

Magnetic field gradients were incorporated into the selective COSY exp eriment. The new gradient-selected experiment has the expected advanta ges of significantly improved spectral quality resulting from better a rtifact suppression and the capacity to acquire spectra using fewer sc ans. A sample of brucine was used to evaluate the experiment and the r esulting spectra were of excellent quality. These experiments may be i mplemented on commercial instrumentation.
