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.

NSERC Discovery Grant申请的主要重点是复杂有机气相分子的精确光谱和表征，具有重要的基础和实际意义。正在研究的分子是：(1)已知对探测基本常数的变化具有更高灵敏度并已知可促进扭转介导的振动能量再分配的含有内转子的物种；(2)天文学界迫切需要其数据以了解硫化学和致密分子云中的“丢失硫”问题的含硫分子。
