Vibrational energy transfer in HF–HCN, DF–HCN, and H2–HCN mixtures

Abstract
Measurements of probabilities for vibrational energy transfer are presented for the temperature range 240–450 °K for HF–HCN and DF–HCN gas mixtures. Energy transfer probabilities in these mixtures exhibit a strong inverse temperature dependence over this temperature range. Rate measurements are also given for vibrational energy transfer in H2–HCN mixtures at 298 °K. The present results suggest the feasibility of cw chemical laser operation in HF–H2–HCN mixtures on the 3.85 μ HCN(001) →HCN(010) band.
