Comparison with a structurally related monoradical (PTM-TEMPE) or mixtures of the two monoradical components reveals that the biradical has a much higher polarization efficiency and a faster polarization buildup. This offers the possibility of faster recycling further contributing to its efficiency as a polarizing agent.4 p.application/pdfeng(c) American Chemical Society , 2014Polarització (Física nuclear)Polarization (Nuclear physics)info:eu-repo/semantics/article6441452018-09-26info:eu-repo/semantics/openAccess
