Abstract
NMR spectra of several styrene, stilbene and stilbazole oxides have been determined, and chemical shifts and coupling constants have been correlated with cis‐and trans‐configurations. Assignments have been made for all protons, and double resonance technique and 13CH coupling constants have been used in some particular cases. An explanation is proposed for the observation that chemical shifts of oxirane protons are higher for cis than for trans isomers.Keywords
