Systems and methods are disclosed for increasing a nuclear spin polarization of a target compound. In accordance with such systems and methods, a first non-thermal equilibrium nuclear spin polarization can be imparted to at least one source atom of a source compound, the source atom having a nuclear gyromagnetic ratio of at least 12 megahertz per tesla (MHz/T). A first solution can be obtained that includes the source compound and a target compound. The at least one source atom can be present in a source concentration of at least 0.1 molar (M) in the first solution. A second non-thermal equilibrium nuclear spin polarization of at least 0.01% can be imparted to the at least one target atom of the target compound via a nuclear Overhauser effect (NOE) transfer of the first non-thermal equilibrium nuclear spin polarization to the at least one target atom.

Systems and methods for generation of hyperpolarized materials

Systems and methods are disclosed for increasing a nuclear spin polarization in a target compound. Nuclear spin polarization can be increased by obtaining the target compound or a precursor of the target compound. The target compound or precursor can include a first proton and a second proton sharing a singlet spin order and a third proton coupled at least to one of the first proton or the second proton. A target atom can be coupled to at least the third proton. The precursor can be placed within a mean magnetic field strength below 500 mT. A magnetic resonance (MR) pulse sequence can be applied to the precursor. the MR pulse sequence configured to transfer population from the first and second protons to the target atom, thereby imparting a non-equilibrium nuclear spin polarization of at least 1%, 2%, 5%, 10%, or 20% to the target atom.
