Cross polarization from (1)H to quadrupolar (6)Li nuclei for dissolution DNP


Perez Linde, A.J., et al., Cross polarization from (1)H to quadrupolar (6)Li nuclei for dissolution DNP. Phys Chem Chem Phys, 2014. 16(45): p. 24813-7.


Cross polarization from protons to quadrupolar (6)Li nuclei is combined with dynamic nuclear polarization of protons at 1.2 K and 6.7 T using TEMPOL as a polarizing agent followed by rapid dissolution. Compared to direct (6)Li DNP without cross-polarization, a higher nuclear spin polarization P((6)Li) can be obtained in a shorter time. A double resonance (1)H-(6)Li probe was designed that is equipped for Longitudinally Detected Electron Spin Resonance.
