Highlights

? Simultaneous Overhauser (OE) and Solid effect (SE) DNP was observed in a polymer solution.

? Polarization field variation enables selective measurement of OE- and SE-enhanced spins.

? By this method polymer and solvent 1H nuclear spin relaxation can be studied separately.

? As a result, selectively DNP-enhanced relaxometry provided 6-fold increased precision.
