The bond distances (<I>r</I><SUB>g</SUB>) and angles (<I>r</I><SUB>α</SUB>) in ethyl methyl ether have been determined by gas electron diffraction as follows: average of C(methyl)–O and C(methylene)–O=1.418±0.002 Å, C–C=1.520±0.004 Å, C–H=1.118±0.004 Å, ∠C–O–C=111.9±0.5°, ∠O–C–C=109.4±0.3°, ∠H–C–H=109.0±0.4°, where uncertainties represent estimated limits of experimental error. The two <I>r</I><SUB>g</SUB>(C–O) distances have been estimated independently with the aid of the rotational constants for the <I>trans</I> conformer reported by Hayashi <I>et al.</I>: C(methyl)–O=1.413±0.009 Å and C(methylene)–O=1.422±0.007 Å. The dihedral angle for the <I>gauche</I> conformer, 84±6°, and the relative abundance of the <I>trans</I> and <I>gauche</I> conformers in the gas phase at 20 °C, <I>n</I><SUB>t</SUB>⁄(<I>n</I><SUB>t</SUB>+<I>n</I><SUB>g</SUB>)=0.80±0.08, have also been determined.
