In situ High-Field Dynamic Nuclear Polarization-Direct and Indirect Polarization of [ superscript 13 ] C nuclei

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. In a dynamic nuclear polarization (DNP) experiment, the large Boltzmann polarization of a paramagnetic polarizing agent is transferred to surrounding nuclei by microwave irradiation at the electron paramagnetic resonance (EPR) frequency.[1… CONTINUE READING
