摘要：

The magnetic resonance spectra of fluorine nuclei in some tetrafluorinated pyridines are described, and the values of the shift produced by a substituent in pyridines compared with that produced by the same substituent in benzenes. For the substituents F, Cl, and OH the values of the para-substituent shift is compared with π-electron densities, calculated by a SCF-MO method.
