Abstract
Provided are methods for nuclear spin polarization enhancement via signal amplification by reversible exchange at very low magnetic fields. The spin polarization is hyperpolarization of isotopically enriched heteronuclei by using a catalyst and parahydrogen to create a complex using iridium and applying magnetic fields in the microtesia range to transfer the spin order from parahydrogen to the complex.
