High resolution infrared spectroscopy of ions of astrophysical interest: H35Cl+ and H37Cl+, investigated in a cold plasma

Santiago de Compostela, Facultade de Química,17-21 julio 2017. -- http://www.bienalrsef2017.com/bienalrsef17/HCl+ is a key intermediate of the chlorine chemistry in the Interstellar Media (ISM). It has been detected recently in the mm-wave region, both in space with Herschel mission [1] and in the laboratory [2]. ¿ Now that the Herschel mission is decomissioned, future studies of HCl+ in ISM will probably rely on ground based IR observations. ¿ There is plenty of HCl+ spectroscopic information in visible-UV [3] but it is of limited accuracy (0,04 cm-1); and is very scarce in the mm-wave and IR [4]. ¿ The JPL group had performed an isotope-independent global fit of all available mm-wave and optical data with predictions for v=1-0, without IR data. ¿ The high resolution IR spectra of HCl+ investigated in this work allows to complete and improve the spectroscopic data for the astrophysics community.The authors acknowledge financial support from the U.E through the grant ERC-2013-Syg 610256- NANOCOSMOS and from Spanish MINECO through the grants CSD2009-00038 (Consolider Astromol), FIS2012-38175, FIS2013-48087-C2-1-P and FIS2016-77726-C3-1-PPeer Reviewe
