Phase shifts induced by transient Bloch-Siegert effects in NMR

• Published in: Chemical Physics Letters, vol. 168, num. 3-4, p. 297-303
• Publication date: 1990

It is shown by simulation and expt. that selective pulses designed to invert or excite magnetization over a limited frequency window induce significant phase shifts over a bandwidth much larger than the chosen window. These phase shifts affect all expts. where selective pulses are used after exciting transverse magnetization or generally p-quantum coherence. The phase shifts may be compensated by modifying the phases of the rf pulses during the expts. or in some cases by suitable data transformations. [on SciFinder (R)]
