DF(9≤v≤12)+N2, CO, CO2, and N2O and HF(v=5-7)+COThe V-V fraction in HF self-relaxation is detennined in fast-flow infrared chemiluminescence experiments through the consistent accounting of all HF(v) populations in partially relaxed mixtures. The v-level specific, fractional V-V probabilities /, are measured for v = 2 and 3 using the F + H, and F + CH. generating reactions, and estimates are obtained for v = 4 to 7 using F + HBr and H + F, data. A consistent set off. 's is 0.55±0.lO, 0.30±0.lO, 0.15±0.lO, and zero for v =2,3,4, and 5 to 7, respectively. These values are compared with one recent laser measurement for v = 2 and with the theoretical predictions of semiclassical trajectory calculations.
