Water vapor Fourier-transform spectra (0.015 cm −1 resolution) were analyzed between 9500 and 11500 cm −1 . Accurate values of 557 rotational energy levels, belonging to the interacting vibrational states (041), (220), (121), (022), (300), (201), (102), and (003) of the first decad of H 2 16 O, were determined. Moreover, 718 line intensities were accurately measured (7% uncertainty). To increase the number of experimental intensities (needed for atmospheric applications), a faster method, using the measured line depths, has made it possible to obtain 1695 additional intensities, with an average uncertainty of about 15%
