3,3,6,6-tetrametyl-1,2,4,5-tetrathiane, [(CH3)2CS2]2,was prepared and the corresponding infrared and Raman spectra were measured.The observed bands were assigned to the different normal modes of vibrationafter a DFT calculation of the molecular vibrational properties. Theexperimental vibrational data and the corresponding assignments weresubsequently used as a basis for the definition of a Scaled Quantum Mechanics(SQM) force field for the studied molecule. A comparison of force constants and geometricalparameters was made with related molecules.
