Novel Strategy for Assigning Hyperfine Shifts Using Pulsed-Field Gradient Heteronuclear Multiple-Bond Correlation Spectroscopy
In an attempt to unambiguously assign all hyperfine shifts, pulsed-field gradient and nongradient H-1-C-13 heteronuclear multiple-bond correlation (HMBC) maps of the bis(N-methylimidazole) complex of (5-(o-nitrophenyl)-10,15,2O-triphenylporphyrinato)iron(III) are acquired. It is demonstrated for the first time that the use of pulsed-field gradients for coherence-transfer selection in combination with H-1 detection is a powerful method for obtaining two- and three-bond H-1-C-13 connectivities between hyperfine-shifted resonances.
