EPR methodology

Although pulse EPR and ENDOR techniques are highly effective in the study of  paramagnetic systems, to fully exploit their potential, methods aiming at increasing the resolution and sensitivity need to be developed. In terms of hardware we are constantly improving the sensitivity and performance of our home build W-band spectrometer. In addition, we concentrate on new experiments for sensitivity enhancement and design of  two-dimensional correlation experiments, involving electron-electron and electro-nuclear double or triple resonance experiments. Such techniques increase resolution and facilitate signal assignment.
