Abstract

By means of Fourier transform infrared spectrometry in the emission mode, the terminal rotational energy content has been determined for CO and CO2 in free jet expansions of various gas mixtures. The vibrational excitation required for radiation was achieved by heating the source gas or by exciting it with a corona discharge. Characteristic rotational relaxation rates were determined for each species. The rate for CO2 is always higher than that for CO, and there seems to be very little coupling between the rotational modes of the two species.
