Texte intégralMeasuring trace gases having a notable impact on human health, climate and the stability of the ozone layer constitutes an extremely important challenge. In the coming years, new, higher sensitivity satellite instruments will improve atmospheric sounding only if the necessary spectral parameters are available. For some species of atmospheric interest such as nitrous acid (HONO) and hypobromous acid (HOBr), spectroscopic data are incomplete or almost non-existent. The challenge in this thesis is to get quantitative spectroscopic parameters for these species. To achieve this objective, an innovative instrumental set-up involving the simultaneous use of two instruments, an IR/THz dual beam experiment, has been built: a thermostatically controlled cell (200-350K) made of inert materials, glass and Teflon, capable of accommodating a 0.1-1.1 THz spectrometer and coupled to a high resolution (HR) Fourier Transform spectrometer (FTS) in the IR range. The THz spectrometer allows to select rotational lines of the target molecule for partial pressure determination, and the FTS enables simultaneous measurement of the rovibrational spectrum in an IR atmospheric window for quantification of the species of interest. The adopted strategy relies on the fact that the intensities of the rotational spectra simply depend on the permanent dipole moment of the molecule of interest, determined with high accuracy from Stark effect measurements. In the case of HONO, which only exists in laboratory conditions in the form of an equilibrium mixture with other species like H2O, NO and NO2, the lack of knowledge of the partial pressure in the gas mixture leads to serious difficulties for quantitative measurements. In addition, HONO exists in two conformer forms, and the height of the conformer barrier between cis- and trans-HONO DeltaCis-Trans is still poorly known, which affects lines positions and especially lines intensities. To improve the determination of the energy difference between the ground vibrational state of the cis- and trans-HONO conformers of HONO, high resolution spectra were recorded in the 50-200 cm-1 spectral region at three different temperatures (240, 270 and 296 K), using the synchrotron radiation of the AILES beamline at SOLEIL. Precise modelling has been performed and were used to determine the height of the conformer barrier DeltaCis-Trans = 95.8 ± 9.2 cm-1. Our value is in good agreement with the previous determination by Sironneau et al (99 ± 25 cm-1), but we have improved the accuracy of this determination by a factor of 2.6. We used this new value of DeltaCis-Trans and the dipole moment parameters for a synthetic spectrum calculation. A precise line list in the far-IR region (0 - 200 cm-1), including positions and absolute lines intensities was generated and, proved to be more robust for an improved detection of HONO in astrophysical objects. To determine absolute intensities in the mid-IR region where HONO is currently detected, simultaneous IR/THz spectra were recorded at LISA using innovative instrumentation developed during this thesis. A first modelling of these spectra is presented in this thesis, and in fine will lead to a much more precise line list for HONO in the 730 - 920 cm-1 region, which will be provided to the scientific community via the HITRAN and GEISA databases and used in the analysis of satellite observations. Regarding HOBr, the aim will be to generate a spectroscopic database in the IR region around 8.6 um, to be used by IASI-NG and FORUM for detection and quantification in the Earth's atmosphere. HOBr plays an important role in atmospheric chemistry and, only exists in laboratory conditions in a mixture characterized by chemical equilibrium: H2O + Br2O = 2(HOBr). The methodology and experimental tools developed during this thesis will be an advantage for implementation of this project, which constitutes the outlook for this work
