Boosting Dissolution Dynamic Nuclear Polarization by Cross Polarization
J Phys Chem Lett.
.
Abstract
The efficiency of dissolution dynamic nuclear polarization can be boosted by Hartmann-Hahn cross polarization at temperatures near 1.2 K. This enables high throughput of hyperpolarized solutions with substantial gains in buildup times and polarization levels. During dissolution and transport, the (13)C nuclear spin polarization P((13)C) merely decreases from 45 to 40%.
Keywords: TEMPO; cross polarization; dissolution DNP; hyperpolarization; radicals.
