Use of Eu(DPM)3 to study the long-range spin-spin coupling of1H-1H and1H-14N via the PMR spectra

  • 15 Accesses

Conclusions

Employing heteronuclear double resonance and paramagnetic additives it was established that the additional broadening of the signals in the PMR spectrum of 1-vinylimidazole is caused by the1H -14N spin-spin coupling, while in the spectrum of 1-vinylpyrazole it is caused, in addition, by the long-range1H-1H spin -spin coupling via six bonds.
