Far-infrared high resolution synchrotron FTIR spectroscopy of the nu(11) bending vibrational fundamental transition of dimethylsulfoxyde
We report the first successful high resolution gas phase study of the 'parallel' band of DMSO at 380 cm(-1) associated with the nu(11) bending vibrational mode. The spectrum was recorded with a resolution of 0.0015 cm(-1) using the AILES beamline of the SOLEIL synchrotron source, the IFS 125 FTIR spectrometer and a multipass cell providing an optical path of 150 m. The rotational constants and centrifugal corrections obtained from the analysis of the resolved rotational transitions reproduce the spectrum to the experimental accuracy. (C) 2010 Elsevier B.V.
