| Zusammenfassung: | The coupling of the tunneling- and proton dipolar reservoirs of a weakly hindered methyl group is used to dynamically polarize the rare-spin nuclei by combination with suitable radio-frequency irradiation schemes. H1→13C and H1→15N double-resonance experiments below 60 K in a pure γ-picoline matrix and with 1.5 % N15-acetonitrile as a guest are reported at a field of 5.17 Tesla. |
