我们报道了在远红外区进行的水蒸气的高温光谱测量。新的数据集包含了大量的过渡，其特征是J值大于30，并允许我们达到旋转水位，而这些水位的信息要么不可用，要么不准确。这一新的数据集，以及以前公布的微波、远红外和红外测量，使用弯曲-旋转法的改进版本进行了拟合，使我们能够对水蒸气的高分辨率光谱进行首次分析，对于基态和(0 1 0)态，高达J=30，对于第一个三元态，高达J=27，对于第二个三元态，高达J=19。分析的结果被用来建立一个光谱数据库，支持在高达1500K的温度下进行高分辨率调查。
We report high temperature spectroscopic measurements of water vapor carried out in the far infrared domain. The new data set contains numerous transitions characterized by a J-value larger than 30 and allows us to reach rotational levels of water for which information was either unavailable or inaccurate. This new data set, along with previously published microwave, far infrared, and infrared measurements, is fitted using a modified version of the Bending–Rotation approach and allows us to perform the first analysis of the high-resolution spectrum of water vapor up to J= 30 for the ground and (0 1 0) states, up to J= 27 for the First Triad States, and up to J= 19 for the Second Triad States. The results of the analysis are used to build a spectroscopic database supporting high-resolution investigations performed at temperatures as high as 1500 K.
