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 (010) 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.
