Fig. 5: ELDOR measurements as a function of temperature.

From: Large cross-effect dynamic nuclear polarisation enhancements with kilowatt inverting chirped pulses at 94 GHz

Fig. 5

Temperature-dependent ELDOR measurements on 4-amino TEMPO (50 mM) showing the effectiveness of the inversion pulse under steady-state conditions at optimal repetition rates. The solid lines show normalised field swept echo heights at different temperatures. The dashed lines show normalised field swept echoes taken 4 μs after the chirp pulse at different temperatures. It should be noted that all data were taken at repetition rates optimised for DNP, and all data were normalised to the peak of the spectrum, at a given temperature.
