The CO2-broadening and shift coefficients of H2O lines are necessary to study the planets atmospheres with the carbon dioxide as the main gas. Water-vapor absorption lines broadened by the carbon-dioxide pressure were recorded using the IFS 125 HR Fourier spectrometer. It was applied the quadratic Voigt profile which takes into account the dependence of the broadening and shift on the colliding molecules velocities. Calculations were performed using a semi-empirical method, the rotational quantum numbers vary from 0 to 20.
