Short summary
Typically, low-field Overhauser dynamic nuclear polarization (ODNP) experiments are 1D NMR experiments to study hydration dynamics. Here, we demonstrate the application of ODNP-enhanced 2D J-resolved (JRES) spectroscopy to improve spectral resolution beyond the limit imposed by the line broadening introduced by the paramagnetic polarizing agent. Crucial to these experiments is interleaved spectral referencing to compensate for temperature-induced field drifts over the course of the experiment.
