Expanding the polarizing agent toolbox for liquid-state dynamic nuclear polarization: stability and performance at 14.1 T.
Dynamic nuclear polarization (DNP) in liquids is emerging as a potential technique to increase the NMR signal of routine NMR spectroscopy at high magnetic fields. Monoradicals are utilized as polarizing agents and microwave irradiation is used to transfer the high electron spin polarization to nuclei on nearby molecule...
