The observation of positive or negative enhancements, depending on the substrate, highlights the supramolecular character of the initial polarization‐transfer process13 p.application/pdfeng(c) Wiley-VCH, 2010Espectroscòpia de ressonància magnètica nuclearPolarització (Física nuclear)Nuclear magnetic resonance spectroscopyPolarization (Nuclear physics)Dynamic nuclear polarization using polychlorotriphenylmethyl radicals reveals supramolecular polarization transfer effectsinfo:eu-repo/semantics/article5870812019-07-30info:eu-repo/semantics/openAccess
