Calculated tabulations of H₂O line broadening by H₂O, N₂, O₂, and CO₂ at high temperature

We present calculations of the temperature dependence of H₂O pressure broadening parameters by H₂O, CO₂, N₂, and O₂. They were made for Q-lines with a theoretical model which provides a correct treatment of close collisions and has been widely tested. The results should be useful for Raman spectra calculations. A simple law is proposed to deduce halfwidths of P-and iMines from the Q-line results. The accuracy of this law at high temperature is demonstrated. A simple analytical representation of a constant halfwidth approximation is also given.
