Abstract

A new study footnote{ This work was done under support of the Volkswagen foundation. The assistance of Science and Technology Center in Ukraine is acknowledged (STCU partner project P686).} of the dimethylsulfide ((CH$_{3}$)$_{2}$S) spectrum is reported. The new measurements have been carried out using the Kharkiv spectrometer in the Institute of Radio Astronomy of NASU (Ukraine) and using the Lille spectrometer in the PhLAM laboratory (France). The new millimeter and submillimeter wave measurements cover the frequency range from 49 GHz to 660 GHz. The rotational transitions belonging to the three lowest torsional states of the molecule as well as the new assignments in the FIR torsional band (AILES beamline of the synchrotron SOLEIL) and the microwave data available in the literature footnote{ A. Jabri, V. Van, H. V. L. Nguyen, H. Mouhib, F. Kwabia Tchana , L. Manceron , W. Stahl, I. Kleiner, A&A 589, A127 (2016).} have been analyzed using recently developed model for the molecules with two equivalent methyl rotors and C$_{2v}$ symmetry at equilibrium (PAM_C2v_2tops program)footnote{ Ilyushin V. V., Hougen J. T. J. Mol. Spectrosc. 289 (2013) 41-49.}. In the talk the details of this new study will be discussed.
