| Abstract: | The efficiency of two-dimensional homonuclear 1H 1H NOE spectroscopy in characterizing and fully assigning the 1H NMR spectra of several isomers of meso- or ring-substituted deuteroporphyrins is demonstrated. The carbon resonances of the skeleton and the substituents were fully assigned using two-dimensional reverse heteronuclear shift correlation spectroscopy. |
