The microwave spectrum of <I>syn</I>-acetaldehyde oxime-<I>d</I> was investigated in the frequency region 7.5∼35 GHz. Several a-type R-branch transitions were identified and the following rotational constants in MHz were obtained: <I>A</I>=45682, <I>B</I>=4057.21, <I>C</I>=3806.13. The transitions of <I>syn</I>-acetaldehyde oxime-<I>d</I> are split into the A and E species by tunneling of the methyl group through the potential barrier hindering the internal rotation. From these separations the height of the barrier was determined to be 1948 cal mol<SUP>−1</SUP>. The dipole moment of the molecule was determined to be 0.938 D from the Stark effect.
