Abstract. In rapid-scan EPR, the magnetic field is scanned through resonance in a time that is short relative to relaxation times. The signal is recorded with a quadrature mixer at the resonance frequency. Relaxation-time-dependent effects on the trailing edge of the signal are removed by deconvolution, giving the absorption spectrum.A previously reported rapid scan (RS) electron paramagnetic resonance (EPR) imaging instrument was upgraded by the incorporation of ADiC. RS spectra and an in vivo image of oxygen in a mouse tumor model have been acquired using the upgraded system. ADiC robustly sustained critical coupling of the resonator to the transmission line during these ... We would like to show you a description here but the site won’t allow us. In rapid-scan EPR the magnetic field or frequency is repeatedly scanned through the spectrum at rates that are much faster than in conventional continuous wave EPR.

Feb 1, 2011 · Rapid scan EPR means that transition through resonance occurs in a time that is short relative to electron spin relaxation times. This causes oscillation in the recorded signal. The slow scan signal can be recovered by deconvolution [1], provided that the excitation of the spin system produces a linear response [1], [3]. To further increase the sensitivity of the EPR technique, especially for samples with long relaxation times, the rapid-scan EPR (RS-EPR) technique has been introduced (Eaton and Eaton, 2016). The advantage of the RS technique as compared to CW-EPR is that much higher microwave excitation fields ( B 1 ) can be applied to the sample before ...Rapid-scan EPR is sensitive to RF/microwave source noise and to baseline changes that are coherent with the field scan.
