| Zusammenfassung: | The proton and carbon-13 nuclear magnetic resonance spectra of bicyclobutane have been analyzed in detail. The use of information from NMR spectra of bicyclobutane in a nematic solvent permits an unambiguous assignment of all chemical shifts and spin–spin interactions to specific nuclei. Some of the assignments differ from previously published ones. A long-range indirect spin–spin coupling of 5.9 Hz is found between the two exo protons, and an indirect coupling of 16.0 Hz is observed between the exo proton and the carbon-13 to which the other exo proton is bonded. |
