Abstract

The carbon-rich molecular ions C₃H^＋ and HC₃O^＋ have been studied for the first time at high spectral resolution in the $5 μ m$ wavelength regime employing leak-out spectroscopy of their $ν_{2}$ (C₃H^＋) and $ν_{3}$ (HC₃O^＋) vibrational fundamentals. All measurements were performed in a newly built cryogenic 22-pole ion trap apparatus, the COLtrap II instrument. Besides the action spectroscopic characterization the new measurements have also been used towards optimization and an improved understanding of the leak-out process via a semi-quantitative kinetics model for which some rates are determined or estimated and rationalized.

C3H+和hc30 +的CC拉伸模式的反振动谱

利用ν2 (C3H+)和ν3 (hc30 +)的漏出光谱，首次在5μm波长范围内对富碳分子离子C3H+和hc30 +进行了高光谱分辨率的研究。所有测量均在新建的22极低温离子阱COLtrap II仪器中进行。除了作用光谱表征外，新的测量还被用于通过半定量动力学模型来优化和改进对泄漏过程的理解，其中一些速率被确定或估计并合理化。
