论文摘要
我们介绍了放射性甲烷的基本不对称拉伸振动带$ {ν_3}(F_2)$的第一个高分辨率测量和旋转分析。使用中红外连续波光学参数振荡器和悬臂增强的光声检测器组成的光谱仪,以确定43个摇摇欲坠线的波数。光谱模型可以在实验准确性中重现所有观察到的过渡波数。我们的工作有助于基于激光光谱法发展放射性甲烷探测器。
We present the first high-resolution measurements and rotational analysis of the fundamental asymmetric stretching vibrational band ${ν_3}(F_2)$ of radiocarbon methane. A spectrometer consisting of a mid-infrared continuous-wave optical parametric oscillator and a cantilever-enhanced photoacoustic detector was employed to determine the wavenumbers of 43 rovibrational lines. A spectroscopic model could reproduce all the observed transition wavenumbers within the accuracy of the experiment. Our work contributes to the development of radiocarbon methane detectors based on laser spectroscopy.
