Temperature dependence of vibrational relaxation in the HF-DF, HF-CO2, and DF-CO2 systems. II

Measurements of vibrational energy transfer probabilities are presented for the temperature range 205-360 K for HF-DF, HF-CO2, and DF-CO2 gas mixtures. The present results provide an accurate determination of the inverse temperature dependence of the energy transfer probabilities exhibited by these systems. Large deactivation effects caused by HF (DF) polymers were observed for temperatures below 220 K.
