Submillimeter-wave spectroscopy of unstable molecules

我们研究计划的主要目标是建立一个亚毫米波和太赫兹瞬态分子光谱的主要设施。该设施采用后向波振荡器（BWO）作为辐射源，并配备了最先进的频率控制和数据采集系统。它将用于研究CH5+等物种的光谱，并在这一令人兴奋的新兴领域培养研究生。亚毫米波和太赫兹区域刚刚为实验室光谱学和空间天文学/航空观测开放。滑铁卢实验室设施将提供不可或缺的实验室数据，如精确的跃迁频率，压力拓宽系数，偶极矩，以及仅作为反应中间体存在的新物种的识别。

The major goal of our research program is to establish a major facility for submillimetre-wave and terahertz spectroscopy of transient molecules.  This facility uses Backward Wave Oscillators (BWO) as radiation sources and is equipped with state-of-the-art frequency control and data acquisition systems.  It will be used to study the spectra of species such as CH5+ and to train graduate students in this exciting emerging field.  The submillimetre-wave and terahertz region has just opened up for laboratory spectroscopy and space astronomy/aeronomy observations.  The Waterloo laboratory facility will provide indispensable laboratory data such as precise transition frequencies, pressure broadening coefficients, dipole moments, and the identification of new species which only exist as reaction intermediates.
