Here, we show a scalar-coupling dominated H-1 O-DNP, using polyaniline as a heterogeneous polarizing agent in an aqueous solution.Chemistry, MultidisciplinaryChemistry, PhysicalSpectroscopyChemistrySpectroscopyheterogeneous polarizing agentoverhauser dynamic nuclear polarizationpolyanilinescalar couplingdynamic nuclear-polarizationenhancementliquidssignalstext::journal::journal article::research article
