Protons with13C-satellite spectra from 1,3-butadiene dissolved in four different liquid-crystal solvents have been analyzed. The observed direct couplings, corrected for harmonic vibration as well as for correlated deformation, show that the trans isomer is dominant but that there must be a low concentration (2%) of a second rotamer, probably close to cis. The structure of the trans isomer is determined and the bond contributions to the order tensor are measured.
