Journal of Magnetic Resonance Nr. 1, Jg. 124(1997), S. 165-171, doi: 10.1006/jmre.1996.1023.http://hdl.handle.net/2003/25711http://dx.doi.org/10.17877/DE290R-3306The far-off-resonance performance of several line-narrowing sequences is investigated. Both theoretically and experimentally, it is found that transverse relaxation times, dominated by dipole–dipole interactions, are most effectively prolonged not only on-resonance but also for certain, generally large, resonance offsets. These correspond to a situation when, during the basic pulse separation, the frequency offset rotates the toggling-frame Hamiltonian by multiples of 180°. The implications of these results for the study of macroscopic translational diffusion using static-field-gradient NMR are discussed.enCopyright © 1997 Academic Press.
