• Microwave spectra of normal, <SUP>13</SUP>C-, and <SUP>34</SUP>S-isotopic species of ethylene episulfone have been investigated. Analysis of the spectra shows that the molecule has the C<SUB>2<I>V</I></SUB> symmetry. The structural parameters obtained from the spectral data for the normal and <SUP>13</SUP>C-ethylene episulfone are: <I>r</I>(C–C)=1.590±0.011 Å, <I>r</I>(C–S)=1.731±0.006 Å, <I>r</I>(S–O)=1.439±0.006 Å, ∠CSC=54°40′±15′, and ∠OSO=121°26′±30′, on the assumption that the C–H distances and the ∠HCH and ∠H<SUB>2</SUB>CC angles are the same as those of ethylene sulfide. Stark-effect measurements have yielded a value of 4.41±0.05 D for the dipole moment along the <I>a</I> axis. The structure obtained has been compared with those of other related molecules.
