Abstract
The gas-phase molecular structure of dimethyl sulfide, (CH3)2S, has been investigated by means of electron diffraction. By a joint analysis of the diffraction results and the spectroscopic moments of inertia by Pierce and Hayashi, the structure parameters, the distances in rg and the angles in \varphiav, were determined (with parenthesized limits of error) to be as follows: S–C=1.807(2) A, C–H=1.116(3) A, ∠CSC=99.05(4)°, and ∠HCH=109.3(5)°. A tilt of 2.35° and the local C3v symmetry of the methyl groups were assumed. The isotope effects of deuterium substitution were examined, and the DCD angle was found to be larger than HCH in the zero-point average structure.
