摘要

我们提出了一种基于QCL的吸收光谱装置，该装置采用150 K的斯特林冷却圆形多通吸收电池。我们报道了第一次高精度测量团块12C18O2和12C17O18O，以及特定位点丙烷同位素体。

Cool mid-IR Absorption Spectroscopy of cold Molecules

We present a QCL based absorption spectroscopy setup with a Stirling cooled circular multipass absorption cell at 150 K. We report the first high-precision measurements of clumped 12C18O2 and 12C17O18O, and of site-specific propane isotopomers.
