 Abstract: The method of 2D exchange NMR spectroscopy is applied to deuterium spectra of bullvalene-d10 dissolved in a nematic solvent. The 2D spectra were obtained by combining Zeeman- and quadrupole-order experiments, using three-pulse sequences consisting of a excitation pulse followed by 54.7° alignment and monitoring pulses. The measurements were done at 5°C where the Cope-rearrangement reaction in bullvalene is too slow to affect the width of the lines, yet sufficiently fast to yield exchange cross peaks. The intensities of the diagonal and cross peaks were measured as function of the mixing time in the three-pulse sequences. A theoretical analysis of the expected dependence of the peak intensities on the mixing time in the presence of the Cope rearrangement is presented and the results are compared with those of the experiments.
