Notes:
Variable temperature fluorine magnetic resonance spectra have been obtained for 1-fluorocyclooctene. At low temperatures both the processes of ring inversion and pseudorotation are slow on the NMR time scale, and two distinguishable conformations can be observed with a free energy difference of 95 cal/mole and a fluorine chemical shift difference of 6·7 ppm. A process with a free energy of activation of 6·1 kcal/mole interconverts the two conformations.
