Abstract:Dynamic nuclear polarization (DNP) is routinely used
as a method
for increasing the sensitivity to nuclear magnetic resonance (NMR).
Recently, high-field solid-effect DNP in viscous liquids on 1H nuclei was demonstrated using narrow-line polarizing agents. Here
we expand the applicability of DNP in viscous media to 13C nuclei. To hyperpolarize 13C nuclei, we combined solid-effect 1H DNP with a subsequent transfer of the 1H polarization
to 13C via insensitive nuclei enhanced by polarization
transfer (INEPT). W… Show more
