Abstract
From an investigation of the 19F n.m.r. spectrum of a fully halogenated cyclohexene it has been possible to derive several types of F-F coupling constant. Even though interconversion is probably taking place, the molecule has one predominant conformer at room temperature hence the coupling constants may be taken as referring to those in the “fixed” molecules. The magnitudes of the coupling constants appear to be angularly dependent and a spatial mechanism can provide only a small contribution to the coupling.Keywords
