The rotational isomerism of the title compound, CH2=C(CH3)OCH3, has been studied by i.r. spectroscopy.The spectrea reveal the presence of two conformational isomers in the fluid phases.The energy difference between them is estimated to be 0.85 kcal/mole in the liquid state.From the shapes of the band envelopes in the vapour phase spectra evidence is obtained that the more stable isomer has a planar configuration of the heavy atoms.A vibrational assignment of the observed fundamental bands has been attempted on the basis of characteristic group frequencies.
