Two types of data have been recently obtained for water: \\begin{itemize} \item Accurate frequencies have been measured for transitions in the sub millimeter and terahertz domains involving high-lying rovibrational levels up to the first triad. 149 transitions have been measured between 300~GHz and 2~THz and 26 from 2.5 to 2.7~THz. These $b$-type transitions take place within one of the five first vibrational states. \item Far infrared transitions involving high-lying rovibrational levels have been recorded recently in the 50 to 600~cm$^{-1}$ region using the emission spectrum of a continuous flow of water vapor rovibrationaly excited by an electrodless radio-frequency discharge.~{\bf 423} (2006) 376.} 3793 transitions with $\Delta K_a = 1$ within one of the five first vibrational states of the molecule have been assigned so far and involve $J$-values up to 25 and $K_a$-values up to 15. There remains a large number of unassigned transitions involving either higher lying vibrational states, larger values of $\Delta K_a$, or taking place between different vibrational states. \\end{itemize} The paper will focus on the results of the analysis of a large data set consisting of already published data~{\bf 251} (2008) 339.} and of the two new data sets. The number of data is equal to 20491 and the bending-rotation theoretical approach~{\bf 181} (1997) 246.} will be used for the energy level calculation. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title ANALYSIS OF NEW DATA SETS PERTAINING TO THE WATER MOLECULE en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
