| Abstract: | Tetramethylsuccinic anhydride has been studied by gas electron diffraction. A nonplanar ring was obtained, with torsional angles φ(C5O1C2C3) = 10.6 ± 1.5°, φ(01C2C3C4) = 26.5 ± 3.2° and φ(C2C3C4C5) = 30.4 ± 4.0°. Torsional angles calculated by the molecular mechanics method were in fairly good agreement with the experimental values. |
