WebA nuclear magnetic resonance study of cyclooctatetraene (COT) in a number of different nematic solvents covering a wide temperature range (− 35 to 170°C) is reported. Proton spectra for both normal COT and partially deuterated COT under conditions of deuterium decoupling were studied. From an analysis of the spectra in terms of direct dipolar … WebExpert Answer. 100% (1 rating) Cyclooctatetraene is a tub shaped an …. View the full answer.
