NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY. TEMPERATURE DEPENDENCE OF THE SPECTRUM OF FLUOROCYCLOOCTATERAENE.

Abstract

The fluorine n.m.r. spectrum of fluorocyclooctatetraene has been shown to be temperature dependent between 30C and -65C. This is attributed to changes in the rate of an inversion-bond shift process which is slow on the n.m.r. time scale at low temperatures. The free energy of activation for inversion is approximately 12 kcal/mole at -33C. (Author)
