In magnetic resonance, the bulk magnetization of a sample that is being measured is typically defined as a quantity proportional to spin polarization. The fact that all spins of the same type contribute equally to measurable signals is considered obv

Abstract Hyperpolarization has become a powerful tool to enhance the sensitivity of magnetic resonance. A universal tool to hyperpolarize small molecules in solution, however, has not yet emerged. Transferring hyperpolarized, labile protons between m
