If each of the ten CH groups were individually labeled, there would be 101/3, or 1,209,600, different ways of arranging them in the Structure 90.181 Doering and Roth pointed out that observation of a single line in the proton magnetic resonance spectrum would mean that all of these structures were simultaneously present and rapidly interconverting.182 Later in the same year Schroder announced the synthesis of bullvalene and reported that the proton magnetic...
