Abstract

It has been discovered that the chemical shifts of carbon atoms in  13C NMR spectra of oximes having pyrrolyl, furyl, benzofuryl, thienyl, and pyridyl  rings as substituents are changed systematically on
going from the E- to the Z-isomer. This makes it possible to use the indicated chemical shifts for establishing the configuration of oximes with heterocyclic substituents and studying the special features of their electronic structure.
