<p>A method for achieving plane rotations using symmetrical adiabatic and composite pulses provides that the pulses are generated to include a pair of symmetrically positioned discontinuous phase shifts (Ζ1, Ζ2) of equal but opposite magnitude and, in the case of adiabatic pulses, a flip in the effective Be executed concomitantly with the discontinuous phase shifts. Methods of spectral editing utilize the symmetrical pulse form with the discontinuous phase shifts (Ζ1, Ζ2) accomplished with predetermined delays between segments of a pulse.</p> |
