Influence of deuteration in the glassing matrix on 13C dynamic nuclear polarization

Phys Chem Chem Phys. 2013 May 21;15(19):7032-5. doi: 10.1039/c3cp50750e.


Replacement of protons by deuterons in the glassing solvents led to 2-3-fold improvement of the (13)C dynamic nuclear polarization (DNP) solid-state NMR signal for samples doped with large electron spin resonance (ESR) linewidth free radicals galvinoxyl, DPPH, and 4-oxo-TEMPO. Meanwhile, the reverse effect is observed for (13)C DNP using small ESR linewidth free radicals BDPA and trityl OX063.
