The weakly bound complex is formed in a pulsed supersonic slit-jet expansion of a dilute gas mixture of carbon disulfide in helium. Contrary to the planar slipped-parallel geometry previously observed for (CO2)2, (N2O)2, and (OCS)2, the CS2 dimer exhibits a cross-shaped structure with D2d symmetry. Two bands were observed and analyzed: the fundamental (C\u2013S asymmetric stretch) and a combination involving this mode plus an intermolecular vibration. In both cases, the rotational structure corresponds to a perpendicular (\u0394K = \u00b11) band of a symmetric rotor molecule. The intermolecular center of mass separation (C\u2013C distance) is determined to be 3.539(7) \u00c5. Thanks to symmetry, this is the only parameter required to characterize the structure, if the monomer geometry is assumed to remain unchanged in the dimer. From the band centers of the fundamental and combination band an intermolecular frequency of 10.96 cm\u22121 is obtained, which we assign as the torsional bending mode. This constitutes the first high resolution spectroscopic investigation of CS2 dimer.<\/jats:p>","DOI":"10.1063\/1.3578177","type":"journal-article","created":{"date-parts":[[2011,4,12]],"date-time":"2011-04-12T08:56:57Z","timestamp":1302598617000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":33,"title":["Spectroscopic observation and structure of CS2 dimer"],"prefix":"10.1063","volume":"134","author":[{"given":"M.","family":"Rezaei","sequence":"first","affiliation":[{"name":"University of Calgary 1 Department of Physics and Astronomy, , 2500 University Drive North West, Calgary, Alberta T2N 1N4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Norooz Oliaee","sequence":"additional","affiliation":[{"name":"University of Calgary 1 Department of Physics and Astronomy, , 2500 University Drive North West, Calgary, Alberta T2N 1N4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Moazzen-Ahmadi","sequence":"additional","affiliation":[{"name":"University of Calgary 1 Department of Physics and Astronomy, , 2500 University Drive North West, Calgary, Alberta T2N 1N4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
