LED Fourier Spectroscopy of H₂¹⁶O in the 14 800–15 500 cm^–1 Spectral Region

Fourier absorption spectrum of water vapor is studied in the spectral region 14 800–15 500 cm^–1 with a resolution of 0.05 cm^–1 and an optical path length of 3480 cm. A detailed list of 906 identified absorption lines of H₂¹⁶O and a set of 426 levels energies belonging to 19 vibrational states are compiled. Fifty-five energy levels are determined for the first time, and the energies of 64 levels are corrected. The comparison with the data available in the literature is made. The error in the positions of well-resolved, not very weak lines is 0.002 cm^–1, and the error in intensities is 10–15%.
