Saturation factor of nitroxide radicals in liquid DNP by pulsed ELDOR experiments.

Abstract

We propose the use of the pulse electron double resonance (ELDOR) method to determine the effective saturation factor of nitroxide radicals for dynamic nuclear polarization (DNP) experiments in liquids. The obtained values for the nitroxide radical TEMPONE-D,(15)N at different concentrations are rationalized in terms of spin relaxation and are shown to fulfil the Overhauser theory.
