Vuichoud, B., et al., Hyperpolarization of deuterated metabolites via remote cross-polarization and dissolution dynamic nuclear polarization. J Phys Chem B, 2014. 118(5): p. 1411-5.
In deuterated molecules such as [1-(13)C]pyruvate-d3, the nuclear spin polarization of (13)C nuclei can be enhanced by combining Hartmann-Hahn cross-polarization (CP) at low temperatures (1.2 K) with dissolution dynamic nuclear polarization (D-DNP). The polarization is transferred from remote solvent protons to the (13)C spins of interest. This allows one not only to slightly reduce build-up times but also to increase polarization levels and extend the lifetimes T1((13)C) of the enhanced (13)C polarization during and after transfer from the polarizer to the NMR or MRI system. This extends time scales over which metabolic processes and chemical reactions can be monitored.

Robust and efficient band-selective magnetization transfer between CO and CA spins can be achieved in highly deuterated solid proteins by dipolar-based homonuclear cross polarization. The approach is designed for moderate magic-angle spinning rates and high external magnetic fields where the isotropic chemical shift difference of CO and CA considerably exceeds the...

We present a novel sampling strategy, interleaving acquisition of multiple NMR spectra by exploiting initial polarization subsequently fromH andH spins, taking advantage of their differentT1relaxation times. DifferentH- andH-polarization based spectra are in this way simultaneously recorded improving either...
