Extensive experimental and theoretical efforts are still needed to provide more accurate databases concerning highly excited rovibrational levels. In this context, the high resolution emission spectrum of water vapor has been recorded between 50 and 600 cm$^{-1}$ using a Bruker IFS 125HR Fourier transform interferometer and a continuous flow of water vapor rovibrationaly excited by an electrodless radio-frequency discharge.~{\bf 423} (2006) 376.} More than 1500 pure rotational lines were assigned within the fundamental (000) and first excited (010) vibrational states up to $J=35$. Rotational as well as rovibrational lines were identified for the higher lying states up to the first hexad. About 1000 pure rotational transitions within the vibrational states of the first hexad were assigned for the first time. The new data, along with a large body of high-resolution data,~{\bf 251} (2008) 339.} was fitted using the bending-rotation theoretical approach~{\bf 181} (1997) 246.} to compute line positions. In a preliminary analysis, the wavenumbers of 1511 new transitions involving the ground and (010) states were accounted for up to $J=27$ with a root mean square value of $0.8\times 10^{-3}$~cm$^{-1}$. Work is still in progress and we are hoping to account for the new data at least up to the second triad. In the paper the new data will be presented and the results of the line position analysis will be given. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title FAR-INFRARED EMISSION SPECTROSCOPY OF ROVIBRATIONALY EXCITED WATER VAPOR en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
