13C NMR spectroscopy has been used to study ring interaction of dipyridyl isomers. It has been shown that there is a direct proportionality between the change in the paramagnetic contribution to the shielding constant and the interplanar angle determined from the PMR spectra. It has also been shown that the interaction between the O-CH bond electrons and thep-electron system of the neighboring ring can affect the magnetic parameters of the substituted C* atom. |
