Short summary
In contrast to adiabatic excitation, recently introduced SORDOR-90 pulses provide effective transverse 90° rotations throughout their bandwidth, with a quadratic offset dependence of the phase in the x,y plane. Together with phase-matched SORDOR-180 pulses, this enables a direct implementation of the Böhlen–Bodenhausen approach for frequency-swept pulses for a type of 90°/180° pulse–delay sequence. Example pulse shapes are characterised, and an application is given with a 19F-PROJECT experiment.
