Strongly scalar 'H intermolecular dynamic nuclear polarization (DNP) of solvent 'H nuclei in solutions of organic free radicals has now been observed at room temperature. Transient protonation of the CFaCOOHIpyridyl imidazoline-l-oxyl radical system accounts for the observed effects.
## Abstract Dynamic nuclear polarization of nuclear spins via the solidβstate and thermal mixing effects is discussed. Continuousβwave Sβ and Xβband microwave radiation have been employed to measure ^13^C signal enhancements and polarization times for ^13^C nuclei in a natural type Ib diamond as a
