我们通过使用JPL倍频链和富山的TuFIR系统，将D2H+旋转跃迁的测量扩展到3 THz。在冷却至液氮温度的扩展负辉光放电电池中产生D2H+。我们观察到五条新的THz线。所有可用的旋转跃迁频率连同来自三个基本频带的组合差异进行最小二乘法分析，以确定分子常数。新的太赫兹测量对于更好地表征光谱特性肯定是有用的。改进的分子常数提供了更好的预测其他未观察到的转动跃迁。
We extended the measurements of the rotational transitions of D2H+up to 3 THz by using the JPL frequency multiplier chains and a TuFIR system at Toyama. D2H+was generated in an extended negative glow discharge cell cooled to liquid nitrogen temperature. We observed five new THz lines. All the available rotational transition frequencies together with the combination differences derived from the three fundamental bands were subject to least square analysis to determine the molecular constants. New THz measurements are definitely useful for better characterization of spectroscopic properties. The improved molecular constants provide better predictions of other unobserved rotational transitions.
