Abstract: The spectra of natural water vapor were recorded in the spectral range 6450–9400cm−1 with a step-by-step Fourier transform spectrometer at room temperature with absorption path lengths up to 1200m. Positions, intensities and self-broadening coefficients of about 11,000 lines were determined. This paper focuses on the intensity parameters: the lines of four isotopologues H2 16O, H2 18O, H2 17O and HD16O were observed and assigned; it presents a new experimental dataset in the 6450–9400cm−1 spectral range. Obtained results were compared to the literature data. Fifty-nine new and corrected energy levels of H2 16O and H2 17O were determined from the vibration–rotation analysis of the observed lines. A brief discussion is added for self-broadening coefficients at the end of this paper. [Copyright &y& Elsevier]
