Dynamic nuclear polarization (DNP) results from transferring spin polarization from electrons to nuclei, thereby aligning the nuclear spins to the extent that electron spins are aligned. Note that the alignment of electron spins at a given magnetic field and temperature is described by the Boltzmann distribution under the thermal equilibrium. It is also possible that those electrons are aligned to a higher degree of order by other preparations of electron spin order such as: chemic… Web-Developing the rapid mixer and freezer devices for the time-resolved solid-state NMR spectroscopy-Structural and kinetic characterization of … sonic and tails first meet
