Abstract

A spectacular failure of F-F spin-spin coupling constants, A_(ij), to decrease monotonically with the number of chemical bonds separating nuclei i and j has been deduced from the nuclear magnetic resonance (n.m.r.) spectrum of perfluorodimethylethylamine. The current importance attached to the use of n.m.r. spectra as a tool for establishment of organic structures prompts us to report a number of similarly anomalous H-F spin-spin coupling constants in cyclobutene derivatives.
