Default Phase cycling with a 240 GHz, free electron laser-powered electron paramagnetic resonance spectrometer

From the The DNP-NMR Blog:

Phase cycling with a 240 GHz, free electron laser-powered electron paramagnetic resonance spectrometer

This is not an article directly related to DNP spectroscopy. However, it shows the tremendous progress made in the development of high-frequency, high-power sources that can be utilized for high-field EPR and eventually DNP experiments.




<div>Edwards, D.T., et al., Phase cycling with a 240 GHz, free electron laser-powered electron paramagnetic resonance spectrometer. Phys. Chem. Chem. Phys., 2013.


http://dx.doi.org/10.1039/C3CP44492A


<div style="text-align: justify;">Electron paramagnetic resonance (EPR) powered by a free electron laser (FEL) has been shown to dramatically expand the capabilities of EPR at frequencies above [similar]100 GHz, where other high-power sources are unavailable. High-power pulses are necessary to achieve fast (

Measurement of rate constants for homodimer subunit exchange using double electronâ??electron resonance and paramagnetic relaxation enhancements Abstract Here, we report novel methods to measure rate constants for homodimer subunit exchange using double electronâ??electron resonance (DEER) electron paramagnetic resonance spectroscopy measurements and nuclear magnetic resonance spectroscopy based paramagnetic relaxation enhancement (PRE) measurements. The techniques were demonstrated using the homodimeric protein Dsy0195 from the strictly anaerobic bacterium Desulfitobacterium...
