Chem. Phys. 79, 2212 (1983); 10.1063/1.446070 Laser double resonance measurements of vibrational energy transfer rates and mechanisms in HF(v = 2)The rate of the resonant vibration-vibration energy-transfer process between mode va of CO 2 and N2 has been measured from 450 o -2600 o K by monitoring the infrared emission from mode Va at 4.26 p. behind incident shocks in CO2-N2 gas mixtures. The data are shown to be in agreement with recent laser fluorescent measurements from 300 o -1000 o K. The combined data for the probability per collision are compared to theoretical calculations and indicate that below 10000K the interaction is dominated by long-range forces and a probability inversely proportional to temperature is obtained, while above lOOOoK the probability increases with temperature and the interaction is due to short-range forces.

“…The CO 2 -CO V-V rate coefficient comes from our previous work [38] and is based on [158], while the rate coefficient for CO 2 -N 2 V-V used in the present work is taken from [159]. We compare in figure 1 the rate coefficients used in this work for the processes (10) and (11) with experimental data available in literature obtained with laser-excited vibrational fluorescence and shock tube techniques by Taylor et al [160], Rosser et al [161], Taylor and Bitterman [162], Stephenson et al [157], Moore et al [163], Starr and Hancock [164], Rosser et al [165], Blauer and Nickelson [159]. Although there are considerable data for CO 2 -N 2 , a large scatter can be observed.…”
