N2 - For decades, the remote sensing measurements have been made in planetary atmospheres in the So- lar System and beyond. As the performance of the space instruments improves, the atmospheric science community is more and more in need of accurate spectroscopic data. The current databases offer some parameters for non-Earth atmospheres but are far from complete for all situations. For example, mea- sured H 2 O line parameters in CO 2 -rich atmospheres such as Mars and Venus are missing while they are of prime importance to learn about the evolution of the atmospheres. New Fourier Transform Spectrom- eter spectra were recorded respectively around 2.7 and 6 μm, using a Connes’ type FT spectrometer built in Reims. The spectra were analysed using a multispectrum fitting procedure to obtain the line-shape parameters of H 2 O broadened by CO 2 . Modified Complex Robert-Bonamy calculations of the half-width, line shift, and their temperature dependence were made in the spectral region from 1300 to 50 0 0 cm −1 . The measurements and calculations are presented and compared with data available in the literature
