The primary focus of this NSERC Discovery Grant application is on precision spectroscopy and characterization of complex organic gas-phase molecules of fundamental and practical importance. Molecules being investigated are (i) internal-rotor-containing species known to have enhanced sensitivity for probing variation of fundamental constants and known to promote torsion-mediated vibrational energy redistribution; and (ii) sulphur-containing molecules for which data are urgently needed by the astronomical community in order to understand sulphur chemistry and the “missing Sulphur” question in dense molecular clouds.
