Ultra-wideband EPR

Sensitivity of conventional pulsed EPR and the possible types of correlation spectroscopy are limited by the insufficient bandwidth of monochromatic rectangular pulses.
Arbitrary waveform excitation, mainly by passage pulses, can overcome such limitations and improve spectral purity by providing better defined excitation bands. We work on excitation schemes with bandwidths larger than 500 MHz at X-band (~9.6 GHz), Q-band (~34 GHz), and W-band (~94 GHz) frequencies.
