✦ Synopsis

The combination of a frequency nonselective excitation suppression method (1337 sequence) with selective excitation followed by gradient-induced dephasing of water transverse magnetization yielded suppression ratios of greater than 10,000: 1. The need for gradient preemphasis and correction of Bo field shifts is discussed. The suppression efficiency of this method compared favorably to results obtained using the CPMG spinecho technique to observe metabolite resonances in a urine sample.

In a recent publication we presented a method to obtain highly resolved NMR spectra in the presence of an inhomogeneous B 0 field with the help of a matched RF gradient. If RF gradient pulses are combined with "ideal" 90 • pulses to form inhomogeneous z rotation pulses, the line broadening caused by

Pulsed high-field gradient in vivo NMR spectroscopy was used to measure diffusional water permeability in cell suspensions of the Gram-positive bacterium Corynebacterium glutamicum. Two different regions of H 2 O mobility were detected. One was characterized by the apparent coefficient of self-diffu

## Abstract 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
