The vibration-rotation absorption spectrum of ¹⁷O-enriched water vapor in the range 14900–15600 cm⁻¹ was recorded for the first time by a Fourier Transform Spectrometer coupled to a multi-pass White-type cell providing an optical path length of 34.8 m at room temperature with a spectral resolution of 0.05 cm⁻¹ using high luminance LED (light emitting diode) light source. The high signal-to-noise ratio allowed for the accurate determination of 1047 positions of water lines, of which 661 lines were attributed to the H₂¹⁷O water isotopologue. The rovibrational assignment was based on new variational calculations, which allowed retrieving 285 experimental rotational-vibrational energy levels belonging to twelve vibrational states of the H₂¹⁷O molecule: (410), (330), (311), (231), (212), (151), (033), (052), (113), (132), (180), and (081). The 3ν₁+ν₂+ν₃, 2ν₁+3ν₂+ν₃ and 4ν₁+ν₂ vibrational bands centered, respectively, at 15325.617, 15095.166 and 15322.533 cm⁻¹, dominate the spectrum. A detailed comparison of the H₂¹⁷O line intensities recorded in this study with observed literature data and with recent high-precision variational calculations showed that the calculated intensities for the (231) - (000) band are weaker by 57% than the experimental ones. The data set obtained in this study will help to improve the quality of variational calculations for water vapor.
