Kurzbeschreibung (Abstract)
C-13 stimulated nuclear polarization (SNP) in acyl-alkyl biradicals has been investigated at a low magnetic field B-0. For carbons in the carbonyl position, which have a strong hyperfine interaction (hfi), a significant SNP effect is observed at low fields B-0 < hfi, in contrast to carbons in the a-position with smaller hyperfine coupling. A qualitative analysis using a two-state biradical model shows that this effect has a strong dependence on the non-spin selective channels of the biradical decay.
