Hydrogen Q‐branch rotational component line‐broadening coefficients for hydrogen–water collisions were determined at 2700 K. For linewidth measurements CARS spectroscopy with a Fabry–Perot interferometer and a multichannel detector was applied. In order to perform these experiments, a high‐pressure pulsed hydrogen–oxygen burner with variable and controlled pressure was designed. Temperature measurements inside the burner were performed simultaneously with the help of broadband CARS spectroscopy. Copyright © 2002 John Wiley & Sons, Ltd.
