A complete line shape analysis of the dynamic NMR spectra of cyclo-octatetraene dissolved in nematic liquid crystalline solvents is presented. The analysis involves simulation of the dynamic NMR spectra in the presence of the bond shift reaction. This is performed using a newly developed group theoretical method. Comparison of the simulated and experimental spectra yield the following kinetic parameters for the bond shift process in cyclo-octatetraene: 1/τ (0 °C) = 2.3×102 s−1; ΔE = 10.62 kcal/mol; ΔH≠ = 10.0 kcal/mol; ΔS≠ = −9.7 e.u.
