The biradical exhibits an extremely high DNP NMR enhancement of >50 000 times, which constitutes one of the largest signal enhancements observed so far, to the best of our knowledge Polarització (Física nuclear) Spin (Física nuclear) Polarization (Nuclear physics) Nuclear spin NMR signal enhancement of > 50 000 times in fast dissolution dynamic nuclear polarization
