Frequency-modulated rf pulses based on a linear frequency sweep are studied experimentally in spin-echo and stimulated-echo sequences. It turns out that these FM pulses generate a quadratic phase perpendicular to the selected slice and that the quadratic phases of the FM pulses in a spin-echo or sti
The application of soft rf pulses in 2D spin echo and quadrupolar echo NMR experiments is discussed. The objective is to measure the homogeneous linewidths of the different single-quantum transitions in systems with large quadrupole splitting where nonselective (hard) rf pulses are not available. Th
