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 knowledge4 p.application/pdfeng(c) Pinto, L.F. et al., 2017Polarització (Física nuclear)Spin (Física nuclear)Polarization (Nuclear physics)Nuclear spininfo:eu-repo/semantics/article6709612019-07-30info:eu-repo/semantics/openAccess
