In this article, we describe the implementation and advantages of shaped pulses in EPR spectroscopy. Phase/amplitude-modulated pulses on a nanosecond timescale allow improved excitation bandwidth and profile, and compensation of spatial field variations. The application of shaped pulses in magnetic resonance is briefly reviewed in the introduction, the frequency responses of some of the most frequently used shaped pulses are outlined in the theoretical part, the implementation of such pulses with EPR spectrometers is described, and finally some recent applications highlighting the potential to improve the performance of pulsed EPR experiments are illustrated
