The structure of thioacetic acid has been investigated by the method of electron diffraction. The molecule was found to have very little resonance interaction between bonds. The interatomic distances found are: C=O=1.24±0.04A; C–S=1.78±0.02A; C–C=1.54±0.06A. The angle CCO was found to be 125°±5° and angle CCS, 110°±5°. The distances assumed are: C–H=1.09A and S–H=1.34A. Angle OCS was assumed to be 125°.
