Articles
Sigma-Aldrich.com presents an article concerning MRI/MRS and the use of isotopes in hyperpolarization.
Dynamic Nuclear Polarization (DNP) is a phenomenon by which high spin polarization, typically derived from a bath of free radical electrons, is transferred to a nuclear spin bath, enhancing the difference between the nuclear energy levels and thereby producing dramatically enhanced NMR signals for detection.
