Determination of the Relaxation Time for the Vibrational Energy of Carbon Dioxide

Abstract

DURING the past year, we have made a series of measurements1 on the absorption of sound in gases at ordinary and low temperatures. As is well known, such experiments are of great interest in connexion with the collision mechanism between molecules. These phenomena can also be studied by means of measurements on the dispersion of the velocity of sound. This method is followed by Eucken and his collaborators2.
