“…Table 1 gives the spectral regions, the number of transitions and the maximal values of the rotational numbers J and K a for the 29 bands. Results of previous studies of the HD 16 O absorption spectra in this region have been published in [15,16,[22][23][24][25][26][27][28][29][30]. According to the recent review of the IUPAC task group [21], overall 5291 transitions have been observed in these previous studies between 8800 .…”

“…The intensities plotted are those from PS calculation since in most previous work no information is provided about absolute intensities. Lines assignments have been made using the results of [27,28,30] (so called ''trivial assignment'') and on the theoretical calculation of the vibration-rotation spectrum of HD 16 O, which was made by S.A. Tashkun. This list is available at http://spectra.iao.ru.…”

“…The HD 16 O spectrum in this region has been the subject of several studies [22][23][24][25][26][27][28][29][30] based on four experimental techniques: ICLAS (IntraCavity LAser Spectrometer), ICLAS-VECSEL (Vertical External Cavity Surface Emitting Laser), PAS (PhotoAcoustic Spectroscopy) and FTS (Fourier Transform Spectrometer). Most of these concentrate on the determination of lines positions and on the rovibrational analysis; they provide assignments and upper energy levels with accuracy close to the experimental uncertainty.…”

O Deuterium a b s t r a c tHigh-resolution water vapor absorption spectra have been measured at room temperature in the 8800-11,600 cm À 1 spectral region. They were obtained using the mobile BRUKER IFS 120M Fourier transform spectrometer (FTS) from ULB-SCQP coupled to the 50 m base long multiple reflection White type cell in GSMA laboratory. The absorption path was 600 m and different H 2 O/HDO/D 2 O mixtures were used. Measurements of line positions, intensities and self-broadening coefficients were performed for the HD 16 O isotopologue. 6464 rovibrational assignment of the observed lines was made on the basis of global variational predictions and allowed the identification of new energy levels. 3n 3 , 2n 1 þ n 3 , 3n 1 þ n 2 , n 1 þ 2n 3 and 2n 2 þ 2n 3 are the five strongest bands. The present paper provides a complementary data set on water vapor for atmospheric and astrophysical applications.

“…The rotational structure of the HDO energy spectrum has been significantly less studied than for the major isotopic modification of water. In [7], results are presented from a study (using an intracavity spectrometer) of the energy structure of HDO in the 9100-9640 cm -1 region; [8] reviews studies of the absorption spectra of this molecule in the 9600-18,350 cm -1 region carried out up to 2003. The combination of the high-sensitivity intracavity method with the use of high-temperature cuvets opens up new possibilities for observing lines with large values of the rotational quantum numbers J and K a .…”

“…To increase the spectral resolution, in the spectrometer a diffraction grating (150 lines/mm) is used, operating at the 12th order of dispersion for the wavelength 1.06 μm. The specifications of the spectrometer are as follows: spectral range 9380-9460 cm The special design of the quartz cuvet made it possible to carry out studies varying the temperature in the range 300-1000 K. Studies of the absorption spectra of HDO in this spectral region were carried out in [7] using an intracavity spectrometer based on a diode laser. In the region 1.0-1.1 μm, the absorption spectrum of HDO was recorded at the common pressure of the mixture of three isotopomers of water, 18 torr, with threshold sensitivity of ~5⋅10 -9 cm -1 and spectral resolution 0.04 cm -1 .…”

In the 9387-9450 cm -1 region at temperatures of 300-1000 K, we have used an intracavity laser spectrometer based on a neodymium laser with threshold sensitivity to absorption 10 -8 cm -1 and spectral resolution 0.035 cm -1 to study the absorption spectrum of D 2 16 O, H 2 16 O, and HD 16 O vapor. The high-temperature spectrum contains more than 450 absorption lines, 240 of which are assigned to the HDO isotopomer. The absorption lines of HDO were identified and belong to nine vibrational transitions: 3ν 2 +ν 3 , 2ν 1 + 3ν 2 , 2ν 1 + ν 3 , 4ν 2 + ν 3 , 7ν 2 , ν 1 + 2ν 2 + ν 3 , ν 1 + 5ν 2 , ν 1 + 2ν 2 , and 3ν 3 -ν 2 .Introduction. This work continues our series of studies of high-resolution spectra of the water molecule [1, 2] and its isotopically substituted modifications in the near IR region, due to transitions to highly excited vibrational-rotational states. The object of investigation was the HDO molecule, whose intracavity absorption spectrum we measured in the range 9387-9450 cm -1 at a temperature of 1000 K.

The absorption spectrum of dideuterated water, D 2 O, has been recorded between 8800 and 9520 cm À1 by intracavity laser absorption spectroscopy (ICLAS) based on a vertical external cavity system emitting laser (VeCSEL) and by high sensitivity Fourier Transform spectroscopy. The combined analysis of the spectra has allowed attributing 1223 transitions to the D 2 O species. The spectrum assignment was performed on the basis of the recent results of variational calculations based on an optimized potential energy surface of D 2 O. A set of 687 energy levels was derived from transitions assigned to eight upper vibrational states, 577 of them being reported for the first time. A detailed line list has been generated. The line intensities were retrieved mainly from the FTS spectrum and the absolute integrated intensities of the 2v 1 + v 2 + v 3 and the v 2 + 3v 3 bands dominating the spectrum have been determined.
