Abstract: | Rotation relaxation of HF in HF-Ar mixtures was observed using a laser infrared fluorescence technique. A specific vibrational-rotational state of HF was excited, and the fluorescence from HF was monitored. Total rotational energy-transfer rates, and individual state-to-state transition probabilities were obtained for υ = 1, J = 3 (ΔJ = ± 1, ±2) and υ = 1, J = 5; (ΔJ= ±1, ?2, ?3). The transition probabilities decreased with increasing ΔEJ,J, the energy transferred from R → T (rotation to translation). The data were fitted to a simple exponential model kJJ, α exp(-ClΔEJ,J'l). C was estimated to be 1.55 ± 0.25 kcal?1 mole. |
