“…The resolution was set to 0.01 cm Ϫ1 for all regions. The three spectra analyzed for this paper were calibrated using our previous measurements on hot H 2 O 11,12 and HDO 13,14 in this region. This means that above 750 cm Ϫ1 our lines have a wavenumber scale that is in excellent agreement with that of Toth 15,16 but the 380-746 cm Ϫ1 region is on a slightly different scale from Toth.…”

Fourier transform emission spectra of D2O vapor were recorded at a temperature of 1500 °C in the wavenumber range 380–1880 cm−1. 15 346 lines were measured, of which the majority were identified as belonging to D2O. The spectrum was analyzed using variational nuclear motion calculations based on spectroscopically determined potential-energy surfaces. Initial assignments were made using a potential surface obtained by fitting a high accuracy ab initio potential. The new assignments were used to refine the potential surface, resulting in additional assignments. A total of 6400 D2O transitions were assigned and 2144 new D2O energy levels were obtained. Transitions involving the 4ν2 and 5ν2 bending states, with band origins of 4589.30 (±0.02) and 5679.6 (±0.1) cm−1, respectively, were assigned for the first time.

New high-resolution water vapor absorption spectra were obtained at room temperature in the 4200-6600 cm À1 spectral region by combining Fourier transform spectrometers (FTS) with single and multiple reflection cells. With absorption paths from 0.3 to 1800 m in pure and air diluted water vapor, accurate measurements of about 10400 lines in an intensity range from 10 À29 to 10 À19 cm/molecule have been performed. Positions, intensities, self-and air-broadening coefficients and air-induced shifts were determined for the H 2 16 O, H 2 17 O, H 2 18 O and HDO isotopologues. The rovibrational assignment of the observed lines was performed with the use of global variational predictions and allowed the identification of several new energy levels. One major contribution of this work consists of the identification of 3280 new weak lines. A very close agreement between the new measured parameters and those listed in the database is reported as well as between the observations and the most recent variational calculations for the positions and the intensities. The present parameters provide an extended and homogeneous data set for water vapor, which is shown to significantly improve the databases for atmospheric applications, especially in the transmission windows on both sides of the band centered at 5400 cm À1 .
