Abstract

Replacement of protons by deuterons in the glassing solvents led to 2-3-fold improvement of the 13C 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 13C DNP using small ESR linewidth free radicals BDPA and trityl OX063.
