DNP

Dynamic Nuclear Polarization (DNP)


DNP takes advantage of the very high Boltzmann polarization of unpaired electron spins that can be transferred via dipolar or scalar coupling to nuclear spins thereby drastically enhancing the NMR signal. For DNP experiments free radicals have to be added to the sample and the electron paramagnetic resonance (EPR) transitions of the electron spins have to be saturated by microwave irradiation resulting in the transfer of the electron spin magnetization to nuclear spins.
